If I visited this page:

https://cran.cnr.berkeley.edu/bin/windows/base

and found Zip builds I would use those. Not only do those not exist, but the
installer has been created in such a way that it cant even be extracted from.
Just because you dont recall it, doesnt mean the demand isnt there. The R
community isnt exactly reachable:

So bugs and feature requests cant even be posted to bugzilla. Then regarding the
mailing list, even if subscribed you cant post, as all posts are moderated.
Compare to other languages, where you just log in an post an issue:

- https://github.com/crystal-lang/crystal/issues
- https://github.com/dart-lang/sdk/issues
- https://github.com/dotnet/coreclr/issues
- https://github.com/JuliaLang/julia/issues
- https://github.com/ponylang/ponyc/issues
- https://github.com/ziglang/zig/issues

If R team is happy with current status quo, then do nothing. If they are
interested in growing the userbase this might be one way to do it.
