Of course in this case it's not from Apple itself, but still a great idea!
Does it mean I can bring back 1password with 1 click instead of 3? (If I forget MacOS is stupid and minimise it) That would be amazing!
Personally though, I always close it - as it's trivial to call it with ⌘\ .
Some of us take it personally if we cannot do everything using only the keyboard.
I use a Mac now (because Windows + Windows admins always manage to mess up something and ny current employer doesn't support Linux as wholeheartedly as my last one) and I like it a lot better than last time I used a Mac back in 2009 - 2012 but there is no doubt in my mind that classic Windows UX and several Linux DEs (while not as polished) have much better UX for keyboard people like me.
And yes:
I have used almost every mainstream desktop environment from 1994 - now (except versions of Mac before 2009 and between 2009 and until somewhere a couple of years ago).
For example, I use it to add a shortcut that completely hides or shows Zoom's on screen controls while sreen-sharing, but in a way they don't pop up again if you press ESC (I'm a developer, so ESC is kinda a necessary key).
This one looks polished, if the nag it's bothering you is covered.
Which one is save to clipboard and which one is save to disk? Who knows.
And then there is inconsistency. You're in Finder, where 'return/enter' (for some reason) invokes file rename. Cmd+O to open.
But in a file selector window, say Numbers, 'return/enter' actually opens the file...
