No.  The reason it was removed is because it's not going to be safe to
do when we have trusted extensions.  Perhaps it would be possible to
figure out a way to make it safe, but the reason FROM UNPACKAGED was
created and existed doesn't apply any more.  That PostGIS has been using
it for something else entirely is unfortunate, but the way to address
what PostGIS needs is to talk about that, not talk about how this ugly
hack used to work and doesn't any more.

Thanks,

Stephen
