graphics/opencv has only 28 consumers which isn't that "large". I didn't
document the rename in r438490 because:
- no manual/special steps required (for pkg, poudriere and, probably, synth)
- r423216 wasn't documented as well
- partial upgrades were never supported (e.g. /quarterly packages + /head ports)
- PORTREVISION was bumped to help tools that don't (or incompletely) respect MOVED

Yes.

No but it'd work as well.

Does "pkg upgrade" not work? If portmaster is such a special snowflake
that requires multiplying copypasta in UPDATING for every rename that

Another issue with portmaster is it makes committers (over)think
skipping PORTREVISION bumps like in 20170411 or 20150919 is safe only to
screw up pkg-upgrade(8) as changed ABI doesn't propagate to consumers.
