Yes, some might already use them. However, I think that this is a
minority and we can transition to the new syntax in the next release
while deprecating the old functionality and removing in a following
one.

Not really reserved words, no. Since there is a syntactic difference
between ALDs and extension names (no trailing colon), even the
extension names can be used as ALD names although that is surely not
recommened.
