That would be a good addition. All the higher level libraries that link with libtiff write their own(like ossim) so it would save a lot of duplicate code.

Well, actually, what is the problem with 3rd party libraries? Duplicate code isn't really a valid argument, as within such application you would only use one of that libraries. Duplicate code maintenance might be true, but that is the problem of their authors - and then again libtiff code maintenance is a topic on its own as well (and such new functions wouldn't flawlessly do their job on every possible sort of TIFF from the very beginning; the RGBA functions don't either - but the user expectation would be that everything is handled gracefully for any possible input... possibly huge support overhead)
