Repology is okay for my use-case because I've gotten accustomed to its
quirks. I wouldn't recommend it as a fall-back solution for Guix in its
current form, tho, for the reason above. Does that make sense?

I wrote about the following facts:
- it is difficult to specify a large number of packages,
- when you have specified a large number of packages, the processing is
  slow,
- checking GitHub fails for me.

I don't see any feelings in there.

Fair enough. I meant an external centralized service.

It has no Emacs interface. Nuff said. ;)

Again, I don't know how to specify efficiently many packages, e.g., all
Emacs packages, or all games. Also, reading through a massive output in
the terminal is not very user friendly, IMO.

I don't think solving this is realistic. Dependencies are sometimes very
loose.
