repoman currently doesn't run any ebuild phases as far as I am aware.
For it to be able to warn, it has to run at least the unpack phase;
running the unpack phase of each ebuild in the directory is costly.

For this to actually properly work, it would need to run all phases;
you don't get false positives and it then can actually check the image.

What good use has this? Not much. Maintainers should check the image
themselves; just to name a few this includes 1) unbundling libraries, 2)
checking if everything is present, 3) checking if things are missing
(important run time files, doc, examples and sometimes even source), 4)
checking that needed libraries (eg. readelf) are listed in DEPEND and
in your case 5) checking if things are installed to the correct paths.

Just one check won't make up for the others, _you_ have to check them.

Although; since this is Python, maybe the Python eclasses can do that?
That way you wouldn't have to introduce slower processing in repoman;
since eclasses can do these QA checks at the right moment, during merge.
