That seems to depend on how must weigth you put on clean vs. "messy"
solutions.

Which part of the current checksums.ini problems does the former not resolve?

Isn't the main issue with checksums.ini is the merge nightmare it poses?
I don't see how this will be a big problem with per recipe checksums
files.

A per recipe checksums file is also the one solution I have seen
that would reduce manual work needed for OE developers to
actually maintain checksums.  And face it, we are for the most part lazy :-D

As I also made clear on OEDEM, I think it is important to make things
simpler and easier to work with.  Not cause more mess and come
up with additional hurdless for OE developers.
