Perhaps you could tell us why you do this? Where do you get `contributed
zipfiles' that are actually `ZIPfiles', especially as CRAN has .zip files
you could get instead? Or is the problem in the way you get them?

Nothing stops people with `atypical installations' amending functions to
suit their atypicality, but it is usually better to fix your local
problems that expect your tools to workaround them.
[Analogously, R CMD INSTALL will not install .tgz files on Unix, even
though some people distribute them: they are (equally) not a supported
format.]
