So this is trying to find the revision of a MAJ.MIN firmware release..

Is the MAJ.MIN part supposed to stay constant for a specific version of
a Venus block (say idk, IRIS2) and only the VREV part is supposed to
be updated with both feature and security developments?

Yes Major and minor numbers will be constant for a SPC and only the

revision will be updated with any new release.

+			vminor && (core)->venus_ver.rev >= vrev);
return ((core)->venus_ver.major == vmajor &&
	(core)->venus_ver.minor == vminor &&
	(core)->venus_ver.rev >= vrev);

for readability
Sure, will take care of this in next version.
