I don't think that we need to support anything before 8.3.

8.4 was a substantial revision (which should arguably have been called
9.0) and was released quite some time after 8.3. If we support 8.3 and
8.4, that's really the last two major revisions. Everyone should be
able to use at least one of those, although not everyone can use 8.4.
