The issue with BBash is that running it means sacrificing either Ice Fang (making Zama against Grounds and Dragons) or Wild Charge (making Zama worse against Bulky Waters and the Metal Birds). BBash gives you a win against Clef and other Fairies, while making gimping it against much of the meta. It's a massive double edged... shield
You mention Weavile as bad due to Zama, even though it pairs up incredibly well with Zama, as both can handle each others' counters quite well. Moreover, it's not like any of the three mons you mentioned were pillars of the meta and if they were gone, the meta would collapse. No, all of them are decent at best and already have enough issues in the meta that hold them back. In fact, Rilla has changed HO more than Zama, though that's more due to Rilla's time in the meta.
Also, Volc and Zap don't have to rely on the 30% to do shit to Zama, their attacks do plenty
0 SpA Volcarona Flamethrower vs. 64 HP / 0 SpD Zamazenta-Crowned: 182-216 (53.3 - 63.3%) -- guaranteed 2HKO
0 SpA Zapdos Heat Wave vs. 64 HP / 0 SpD Zamazenta-Crowned: 122-144 (35.7 - 42.2%) -- guaranteed 3HKO

Pro-Ban players claim that Zama is broken as it forces changes onto brawlers in the meta. However, every mon/mechanic causes changes, some a lot more than others, like how Cinderace caused so many Rocky Helmets or how HDB has caused some HO teams to forgo hazards or how Koko used to run HP Ice to handle the threat to Lando who might want to absorb a Volt Switch or how every mon below 120 speed used to run a +Spd nature to have a chance against ScarfTar or how Dragon Dance TTar ran Ice Beam in ADV to hit Flygon or how Snorlax necessitated every team to have a phazer. I could go on and on and on about this, but forcing changes doesn't make a mon OP.
A mon is OP when the meta is forced to run subpar options just to have a chance against it, like Buzzwhole or Seismitoad and even if they have a chance against it, they still fail, like the case with Cinderace. Zaza doesn't force any of that. Rocky Helmet Tox or SlowTwins aren't waste of a slot. Running Volc or Zap on HO doesn't make them worse, in fact, Volc makes it better against Stall.
HO has shown that it is very adaptable and it only peeters out when stuff like Cinderace which warp the tier and force stall to the forefront. It has survived through Dragapult and Rillaboom, two mons that would otherwise devastate HO
Here are the pros and Cons of am SSOU with Zama
Pros | Cons |
A knock-off switch in | No power boost from items available |
Decent typing | Massive 4MSS |
Great Bulk | Easy to wear down with Spikes resurging |
Able to stave off many HO mons | No recovery |
STAB CC | Needs a Howl Boost before it even has a chance to sweep, it doesn't even OHKO Urshifu-R with a Wild Charge at +1 |
Great speed | Two of its strongest moves hinder its bulk (CC's defense drops and Wild Charge's recoil) |
| Due to its move choice, it can be forced out by things it should beat if had the right move |
| Due to its Steel/Fighting type, it can't handle Psychic, Flying and even Fairies if it opts to drop BBash for better coverage, meaning that teambuilding with it isn't that easy |
| Defensive sets are passive and easy to abuse for any stallbreakers or even Ferro, since BBash is preferred there over CC |
As you can see, while Zama has its very good strengths, they are held back by the myriad of issues it has. I believe it would be a decent part of the meta at best and it could even fall down to UU if I am overstating its qualities
