This could be solved by an internal variable that records the maximum version of used PDF features. Then conflicts with \pdfoptionpdfminorversion can be detected and an error or warning can be raised.
Or pdftex could track the maximum of minor version and write this value at the _end_ of the pdftex run (currently it's written at the start, and frozen). There is already a procedure for setting the /Length counts, which can be mis-used, e. g. i have just tried this: @
Also this can be extended by a new primitive, thus that packages such as hyperref also can mark its code with its maximum version number of used PDF features.
