Could be a problem indeed, but only if we are aiming at changing the 
default. We're probably not going to do that, or at least not right away.

My advantage (maybe?) is that I don't use the "switch project" command 
very often. But when I do and I think about it, it kinds of seem to 
stick out compared to some other commands, in particular "prefix" ones, 
that you have two separate key sequences which you need to input, 
instead of just one longer one.

That's where my main motivation for this patch comes (the other being 
that 'C-h' works with it).

Speaking of the implementation strategy, though, I think the current 
other-project-prefix implementation still doesn't work well together 
with project-other-*-command.

I.e. I'd expect 'C-x p P C-x 4 p f' to function as "find file in 
different project", but it both interrupts the key sequence before the 
last char (with a prompt), and ultimately fails to switch to that 
different project.

I think we could add the new command, and then revisit the question of 
defaults in 1-2 years. I guess the main difficulty is documenting all 
the new alternatives added in Emacs 30 adequately, so the user can make 
a confident choice which one to use.
