When running npx create-next-app@latest it now won't let me install it into the current directory (using a . for the app name) as it used to. I also can't use capital letters in the app name... why?

Let me name my stuff the way I want.

All this does is mean that I have to install it to a sub-directory of where I want it, then move everything up a level... it's just a pointless waste of my time for something that used to just work.
