alphabetizing -- I thought that was the prefered order, no?

Well I'm sure there is a sort police out there, everyone has their OCD.
But all in all, it does not matter at all, the order here is irrelevant.
The problem is that it makes it harder to read the diff to see what was added/removed :-)

Should I split out the OCD-part in a separate commit in the future? :D

You should not reorder things :-)
