I don't think so. Diffing my overlay file to the original file in a new
upstream release is more difficult than comparing in-place modifications
(and can hardly be automated). AFAICT, you have to do some merging
anyway, and it's easier if you can use the usual tools.
It helps somewhat for completely new subroutines, but I don't see the
point for tweaks to existing ones.
