No - this conversation is entire about the alternative system.  We are
talking about priorities within the alternative system (as implemented
in other distros).

E.g. when installing python3 and python2 in the same transaction, which
one should be symlinked to /usr/bin/python?

I'm thinking first one installed wins.  It also avoids decisions about
whether pacman should automatically update alternatives to a higher
priority package if it gets installed later.
