I wonder why that is since "git diff" is pretty fast on a local
checkout. Did we ask the gitlab folks about it?

Not necessarily. Maybe a graft would do:

This is IMHO preferable over history rewrites. I've used this to tie
histories in the past. I've not used "git replace" though but
.git/info/grafts.
