There are a couple of lines with:

id = input if input.find("@") >= 0 else input + "@" + mapset

Theres are maybe better written as:

id = input if "@" in input else f"{input}@{mapset}"

But I am not sure if tthat kind of changes are out of scope, so if you rather keep that separate that is fine with me...

Of course, I know about them, and the in is more performant. I saw someone on stack overflow that showed numbers with 10x better (not recent though). I didn't want to shove them in hidden in these big PR (enough to split them in 3). I hoped that the PRs of this weekend would have been merged rapidely so I would have the chance to make the find-> in changes.

So, once this PR, and the following (ready, but not posted yet) are merged, I'll do the changes for str.find() to in. There are some instances of that pattern too if I remember well.
