Yes, same idea as for xyzzy.claranet.de and claranet.de -
I'm that single user xyzzy (a vanity subdomain).  In that
case it's no per-user policy, only a wildcard solution.

publishing %{l} is too high of a risk that the reputation
of the entire domain be tarnished by one single user

If that user publishes +all and spams the world his provider
will kick him and maybe publish -all for some time until the
spam zombies run dry and use another MAIL FROM.

how likely is any domain to want a %{l} in their policies
after they've considered all the implications?

With a working abuse desk it's "only" a support nightmare.
You won't find it for free accounts, it's a premium service.
