Hi Christoph,
Thanks again for the "new version of file in experimental" bugs;
very much appreciated.

Naturally, as one of the maintainers of strip-nondeterminism, I am
inclined to believe that this is a minor regression in file. :)
However, this "extra data prepended" doesn't fit well under the rubric
of "data". Yes, this "#!/usr/bin/python3\n" shebang is definitely
"data" of a kind, but a shebang isn't really data in that way given
the special-treatment afforded to it by UNIX systems. Even if this
noun was replaced by the more general "bytes", the magic nature of the
shebang would still remain… as would the desire to discriminate
between pyzip files and other ZIP files with prepended data.
Could another — different — string be emitted in the case that these
prepended bytes are a shebang? We could potentially look for the file
starting with #! and for that to take precedence over this new case.
Regards,
