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).
