t() did not improve in this regard at all.

No, there is no way, and it does throw the same warnings on core code,
where the same applies. By the way, I'd advise you to upgrade your
potx, since later versions give better warnings and even link to more
docs where you can read details (and do not say criptic things like
"marker error").
