Yes, with a post-build script you have full flexibility, but we have
quite a lot of helper functionality to handle "common" fixups in a
simpler way than though a post-build script, E.G. stripping, removing
.py files, overlays, ..

This restriction for overlays isn't obvious and wasn't originally there
(before the merged /usr support), so it is arguably a regression (but
for an edge case as this afaik is the first report of it).
