IMHO, the sort would not be too expensive; even on all the packages
that Guix already includes now. ;-)
So, it does not matter too much, I guess.

However, the manifest returned is not necessary functional because the
pkg1@v1 and pkg2@v2 are not necessary provided by the same commit.
Therefore we could imagine "options" to the '--export' command, as
'--export=full' or '--export=light' etc. And even '--export=sorted'
and maybe combined as '--export=light,sorted'.
