The above three restrictions are essentially the same as restrictions
acceptable in other DFSG-free works. Good.

This is unusual. It seems to be requiring a changelog for *each file*,
appearing *in that file*. This is a cost that I'm not sure is
Its requirement for the modifier's name to be recorded is also a
concern. I think the “Dissident” test is violated by this.

This is much less a problem; a similar restriction is in the GNU GPL,
and does not appear to violate DFSG.

Renaming requirements are annoying but probably DFSG-free.

This look a bit of an over-reach. I don't know of a DFSG-work that has a
similar clause; it might be too high a bar.

Hard to read because of the SHOUTY CAPITALS, but I can't see a problem.
So the main problem I see is the requirement in condition 4, for a full
changelog in every file that includes every person who modifies it to be
recorded by name.
