regression tests at the macro package (output) level is something else; afaik latex already has regression tests

Oh, very interesting - where are these?

; as said: analyzing the page stream or objects is non trivial, and even simple changes in pdftex or in annot/object/literal support will make a comparison nearly impossible

So maybe for pdfTeX development mainly the bitmap-based tests are useful; but for macro packages, based on a given pdfTeX version, I think the PDF based tests make sense, too.
