 > Should I expect any other side-effects from removing it that I'll need
 to clean up?

 Hard to tell, WordPress core was really written to work exclusively with
 time zone set to UTC for a very long time. There isn't really a clear list
 of what are the effects on core operation, since no one is supposed to be
 doing this in first place.

 Day shift ''should'' probably just go away, since in this case existing
 permalinks are "correct" even though they were generated in "incorrect"
 environment (which is ''now'' breaking how links are generated).
