That may be true for Windows, but as I said is not necessarily true on

I concur with Juha that accepting contributions is much more important
than telling people what not to do because "no native support" really
shouldn't be a big issue for a developer reviewing patches.

On Windows, just installing 7zip (portable) will get you 7z, .tar.gz,
.zip extract support as well as support for a lot of other archives.
AFAIR, same for Peazip (written in Lazarus).

Once people start making regular contributions, zip does seem to be the
most well-supported format in general... either natively, as you said,
or by widely available packages. Even then, a tgz makes a lot of sense
if reporting Linux/OSX/Unix bugs as support for these is often built in
(who knows, it may be always, but I'm not even less of an
AIX/Solaris/BSD expert than a Linux distribution connoiseur)

If some sort of enforcement is to be done (or not), I'd suggest at least
to match decisions; this way we can makes sure there's a consistent
message to patch submitters.

The message we're sending is the reason I brought it up.
