Done. 28 in use; kept as AltLabel.

28 is in use anyway, so...
It can be debated whether https://travelmapping.net/devel/manual/wayptlabels.php#dropa applies.
If not, hey, no problem!
If so, we're good on "If there is another interchange with the same number and different letters, optionally keep the A" grounds.

Going no-build on these per the above rationale. Keeps things consistent with 28N/28A, and keeps a smaller commit history (not that that matters much in a repo with a commit history the size of HighwayData ).
