Transient does the same, and I always found that to be a very natural

The same thing if you just press "C-x" and wait a second.

At the very least these examples demonstrate that it's fine not to show
a cursor.

I agree with both of these ideas, so that we can keep the Emacs
interface a tiny bit more consistent.

Otherwise it will be down to the preference of individual package
authors, who will pick one or the other on a whim or individual fancy.
