That's not the answer. The answer is just to remove the need for class-based
lookups. It'll be less typing anyway.
The trouble is it needs somebody to have a proper think about how to still
DWIM relationships - I had this basically working where you provided an
explicit join condition everywhere but people kept reporting the fact that
it didn't auto-find the PK on the other side of a class that wasn't loaded
yet as a bug and in the end I gave up.
Most of the code is actually still in there, too - if you explicitly define
all your joins and switch to using the source name instead of class name
you're probably good.

Alternatively, a nasty 2-line workaround -
@My::Schema::UserView::ISA = ('My::Schema::User');
$source->result_class('My::Schema::UserView');
proceed as normal :)
