There's one issue, though. Have a look at Ins_MIAP: I have changed
your diff
[...]
to retain the original logic. Please check.
I think this patch restores the actual original logic. No idea if it's a
good idea either way.

Subject: [PATCH] Ins_MIAP: Revert Infinality twilight zone logic to original
In the twilight zone, the Infinality code prevented modifications to the
x-coordinate of points in ignore_x_mode or sph_compatibility_mode.
Commit ed1d8983f3826124e814145b7556fc8f03ae88df changed this to require
being in *both* ignore_x_mode and sph_compatibility_mode. Revert.
