Same here, Julien :-)

Thanks for CCing me, Pierre :-)

Yes, assuming I get accepted for GSoC to work to add Clojars support
to Guix, Julien's work will be indeed helpful, as it would help me
evaluating whether The Central Repository (TCR, the new name of Maven
Central) is "Guixable enough" or not.
(That being said, the relative importance of TCR support for my
project would depend on the way I end up achieving Clojure CLI +
deps.edn support...)

As I mention in my proposal, an important aspect of TCR relates with
which types of package metadata it supports (or not). AFAIK, TCR does
not support explicit licensing and source repository metadata, very
important for Guix's values of freedom and reproducibility...

If full TCR support were to be somehow officially added to Guix, my
hypothesis (yet to be proven or refuted :) is that it should involve
mechanisms to deal with those limitations... Of course, all this does
not mean TCR support could not be eventually implemented as a
non-official Guix channel...
