I agree. It will not. Speaking for me personally, I’m still going to lay spikes and I’m still going to spin block. Not really concerned about Corviknight Defogs since he’s passive af (free switch to breaker). Also the good spikers / rockers beat the removal mons anyway.
Not concerned about Corviknight Defog is kind of ignoring the value of removing hazards for even one turn. Your breaker literally needs to be anywhere from 12-30% stronger to hit a switch-in without/less hazard support, so the fact that Defog worked is already in Corv's favor even if it immediately gets sacced and doesn't survive to do a Slow U-Turn (which isn't exactly an unrealistic thing for Corviknight since its own Hazard Profile can afford Leftovers for one thing).
252 SpA Choice Specs Dragapult Shadow Ball vs. 248 HP / 8 SpD Corviknight: 186-219 (46.6 - 54.8%) -- 10.5% chance to 2HKO after Leftovers recovery
The other thing is that beating the Removers isn't as urgent a requirement if Hazard removal even becomes feasible. One of the trade-offs to Spikes is (theoretically) that they do a lot of consistent damage if you take more turns to set them vs how much work they are to remove. Naturally this makes the concept of Spin-blocking a lot more valuable to Spikes teams, put a lot more pressure on them to position well when Defog became a thing (since you had to pressure them out of it/have Taunt ready rather than being able to reactively stop it), and why they're so huge when Gholdengo stops them for free on top of the narrow removal. We did get several good new Spikes users this generation, to which I argue that still isn't what changed the Hazard Dynamic compared to Gholdengo being an Iron Ball on the already constricted Hazard Removal: Of the Pokemon that gained it this Gen but didn't have it in their last appearance and would realistically see use with it in an OU set, we have: Ting-Lu, Clodsire, Mew, Garchomp, Gliscor (banned), Greninja, Magearna (banned), Meowscarada, and Sandy Shocks. 7 Spikers vs 3-4 Removers isn't as dire as it sounds considering what those ratios were like in previous Generations, and looking just at Corviknight as the central example, 4 of the still-OU guys can't make any more progress against Corv with their Spikes sets or a Standard + Spikes set than it can against them, which is a winning ratio for the Defog-Spikes turn count as well.
"Free" is a label I use because Gholdengo HAPPENS to stop Rapid Spin and Defog, but no one is short-sighted enough to think this is the only or even primary reason for a Mon with 12 Resistances/Immunities, extremely well-distributed stats, and a movepool that includes excellent Coverage/Recovery/"Better Draco" STAB is an OU staple (hell most of the Pro-Gholdengo arguments focus on its defensive checking of several big threats that GaG stopping Defog doesn't factor into heavily).
Another point, not strictly an accusation against your post but one that bothers me, is how the Gholdengo sentiment seems to argue at times that if its removal won't fix the Hazard situation then action against it isn't worthwhile. Even if the problem is still bad, Gholdengo undeniably makes it WORSE while having several other negative impacts on the tier (literal free Utility/Recovery casting use since Taunt is blocked, dominance over anything that is not a strong direct attacker). People having to spin-block with Dragapult or Tera Ghosts is a MASSIVE shift in blocking removal for obvious reason, and this is assuming no other Ghosts rise up to significance without Gholdengo in the tier, whether for Spin-blocking or simply having niches that aren't worth it competing with the tier's best Pokemon (yes I say this over Gambit, who is broken but less tier-defining than tier-stomping as terms I used in a previous post)
