Interesting.  Does this mean that down the road a postgis index
might be GIT-ified?

On my biggest tables (clustered by zip/postal code) the index on
the  geometry  column with a postgis index probably sees all the
rows on each  of it's pages pointing to the same few heap pages.
If I understand right, that's the kind of pattern that GIT helps.
