Do we need to remove the whole hash? The path hash would definitely
break grafts, but why should the content hash break grafts? Having the
content hash would also solve this issue.

Here is the upstream explanation for the hash
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/comp.c?h=194a8f5c1406dd7e762376bdfde78d1b7d01b6b1#n4433
having two parts, path and content hash.
