measures cannot be combined or splitted, if the file already has parts
S5 - Suggestion
If I have a file, where I already extracted parts, then measures cannot be combined or split, at least with the master-nightly. If I delete all parts, it is possible again.

Yes, this was a deliberate choice shortly before the release fo 2.0, as a quick 'fix" to a bug that caused corruption in these cases. See #51401: Split and join measure commands corrupt linked parts. I guess it's time to revisit this.
came up again in the Facebook user group

Note the way split.join works is changed pretty drastically in master - the commands themselves are gone, now it is attached somehow to barlines. Most likely this won't be fixed for the 2.x branch, but it would be good make sure we have a good solution for 3.0
so not a bug, but a missing feature, right?
Workaround of course is to remove the parts, do the split, generate the parts
Yes, but it's an especially lame limitation. I'd have fixed it myself if the implementation hadn't changed so drastically shortly after I disabled it.
