I'm not sure you can do this. For example, bitbake itself doesn't
know/care about *.patch files, however if one is referenced in a
SRC_URI and ends up on the watch list, would this change break a patch
file changing causing task checksums to change?

Its looking like we need better tests for some of this code too :/.

Cheers,
