you can think of it like relaunching a pokemon tbh, I think you see it backwards
to TPC, samurott hisui is, in fact, a direct replacement for original samurott in 2022
it is replacing the original, the 2.0
They do not want to touch the old Samurott, because the point of making starters new forms is to give them new life with new designs and rebrand the Pokemon, competitively and design wise. Samurott-Hisui is, from 2022 onward, the "real" Samurott, while the original is going to be just there
I feel like people here see modern Pokemon power creep as a neutral force.
No, it's not! It's on purpose! What are you talking about? They are actively trying to make the new designs more competitively viable. Iron Valiant is supposed to destructively outclass Gardevoir and Gallade enough for it to be used in competitive, and have merch sold by fans seeing it more and more. Great Tusk is meant to be the New Donphan, the Cooler Donphan, it is outclassing Donphan at everything Donphan does.
Why do you think there has been one Protean Pokemon for 3/4 generations of Pokemon in which TPC has had a more direct eye on competitive (since Gen 6)
Greninja
Cinderace
Meowscarada
Look at this image from before Gen 9 was even announced

Greninja, Charizard, Pikachu, Cinderace. Guess what is absolutely going to be added to Pokemon Unite in the next few months? Meowscarada, and then there will be a prominent one in the anime, it will have a ton of merchandise. It is supposed to be the new cool Protean starter, another iteration.
And to help make sure this happens, they happened to give it exactly 1 single Speed stat point above Greninja, so in any matchup between the two half Dark-Type Protean users, the new iteration will win out, with a super-effective Grass-Type STAB (Flower Trick, which is a clone of one of the most powerful moves in Pokemon history, Wicked Blow) will come out before Greninja can even shift its type.
Competitive is now another venue for Pokemon to increase its profits and get more new Pokemon and try to increase the cast of profitable Pokemon via merchandise.
Look at Smogon custom avatars. How many of them are using a trainer OC alongside a competitively viable Pokemon? That is not by coincidence, they want new appealing Pokemon to succeed so you feel a deeper bond with them. I used to fucking hate Ferrothorn, but after seeing that motherfucker in Smogon for years, I cannot find it ugly anymore, it is just normalized now. And now they want this but for Pokemon they actually think are appealing.
New forms, new evolutions, paradoxes, Megas, Regionals, cross evolutions;
they all serve the same purpose, which is to rebrand a design for a new audience and attempt to capture more appeal. And to help with this, they use competitive viability to push Pokemon into more eyes.
Alolan-Ninetales is not just an alternate Ninetales, it is new and improved Ninetales, with design sensibilities for a new audience. It works, it's literally my third favorite Pokemon of all-time.
