I think you're partially right, but I'm also convinced that Ocean has no brakes. In the sense that every time an idea comes into his head that he thinks is cool, he tries to implement it immediately regardless of time or whether it makes sense.
I do not think this is true, for the most part the changes Ocean has made so far are not unreasonable ones. WiaB remake was for the better, the OG although not without a charme was all over the place with some completly nonsensical scenes.
The changes to SG also are pretty reasonable, he made an investment in the musics and to not use it is throw money away, to edit some crotch out and the spicer scenes to not loose money is understandable in my view. It also helps that it make the game more accessible.
The difference between this changes is that one was born of a creative view the other of pragmatism. One enrichs the story, the other dilutes it. I can't honestly say that Nami paths hits the same way as it did before, is not worse but it also can't be the same.
How the new change affects WiaB is dependent on what motivated this change, the thing is that in this case either way is problematic. If Ocean truly had a change of heart, he loses credibility if it is out of pragmatism, is not the same as cut some crotch in a few renders and will affect the whole game. It can work, but as was said the script will not heal it self and futher change will have to be made to acomodate this one.
That said, is hard for me to believe that Ocean did it on a whim, it was a thought out change. May be that it was a bad decision but I doubt it was done without consideration
