That to me reads as "show me the status of all files ending in .mount in the current directory". Once you start hijacking shell metacharacters you're on dodgy ground.

Except it isn't, because a `*` at the start of a regex is invalid. `-name` patterns given to `find` are explicitly shell glob patterns. You might be thinking of `-regex` patterns, which GNU find also has.
It's a bit shonky when `find` does it because it's not saying "the shell pattern applies in this directory", and I regularly trip over it. It's something special you've got to know about how `find` works, but at least it's still anchored to the idea of being searched in a path that's also part of the command. There's a semantic link there.
With `systemctl status *.mount` you've not even got that. What path is being searched for `*.mount` files? Is that path part of the `systemctl` interface? Or is this just another way that `systemctl` insists on being a special snowflake that someone's decided I now need to devote neurons to?
You could put quotes around it to make it clearer:
The string is matching on unit names, and the mount units have the .mount suffix.
