On the usability / convenience question, we obviously disagree. I
consider that multiplying the test source filters is a more serious
source of annoyance and confusion for the users, but it is a matter of
appreciation and you obviously disagree. For that kind of question the
normal policy would be to ask for the appreciation of other people,
especially the ones who deal with users on a regular basis, before

As for the technical issues, there are two, and the answer must be

This filter includes some amount of boilerplate code, which is a
maintenance burden. Please make more efforts to reduce that. In this
particular instance, I believe using the framework that Stefano designed
for test sources would reduce the boilerplate code.

This filter is not bit-exact. A test source needs very strongly to be
bit-exact. There is in the code base all that is needed to make it so,
and that would make it faster as well.
