I don't think we should worry about that: those who want to read Info
files with something else than Emacs may need to have `gzip` installed,
and I think it's perfectly acceptable.

My question was instead about whether or not Emacs does indeed make use
of `zlib-decompress-region` when it tries to read a gzipped Info file,
and whether the Windows build does always provide
`zlib-decompress-region` or whether that function also requires an
external dependency that may or may not be available (in which case
it's no better than using the `gzip` executable in this respect).
