That part is maintained by Johanned so you need to talk to him.

For all practical matters Ubuntu is 'close enough' -- and for Ubuntu we
have
r2u which supports
i) amd64 and arm64 for the main R package(s) at CRAN,
ii) as well as over 22k CRAN binaries via the r2u apt repo
making it much easier to test with whatever (CRAN) dependencies a package may
have. This works most easily via a container, via GitHub Actions (given GH
has Ubuntu runners) or of course via direct installation.
To be clear, I fully agree with your "wouldn't it be nice if ..."
sentiment
but at the end of the day a volunteer has to step up. If you see something
missing, could you supply it, possibly in coordination with the maintainer of
the existing service?
Cheers, Dirk
