I think all kinds of release schedules have their purpose, but it has to fit the show. The nice thing about streaming is that in theory now you could choose the best model, whereas before one had to adhere to timeslots.

To give some examples:

Andor season 2 released in 4 3-episode blocks, each having a time jump in-between, and it was perfect. Made each one feel somewhat like a movie and have them enough room to breath on their own.
Murderbot released weekly (except the first two episodes together) and that didn't work for me at all, since each episode was so short. Wait a full week to get sometimes less than 30min? No thanks.
On the other hand a show like Severance that is all about the mystery and little details hugely benefits from the weekly release schedule that also allows better discussions.
Just dropping the full season imo works best for shows that are just (to some degree) mindless entertainment. For example I think Amazon could have just dropped the full season of Jack Reacher all at once. In those cases just let people themselves decide how much time at once they want to watch. It hardly matters for the shows quality.
