For my older, smaller projects, nope. For a few projects I'm involved in that are currently in development, I had anticipated porting because of the bugs in 3.x that we were having to work around which are now hopefully solved, though now I'm reconsidering that and it may be better to stick with 3.x just to get the game out of the door. For new projects, it's a toss-up. Until a lot more resources (documentation, tutorials, plugins/extensions) make the shift to 4, it might be wiser to start even completely new projects in 3.x. But the improvements and fixes in 4 are enticing, so if the official Godot documentation is sufficient (admittedly, the official docs are quite well written, and usually it's more of a case of finding stuff than it not existing) and there's no need for extensions that don't exist for 4 yet, then doing with 4 might be a the more future-proof choice.
