Roll back the Test::Builder 1.5 formatting changes?

I'd like people's opinions on a possible downgrade of Test::Builder 1.5
in an attempt to make getting a stable release out easier.  It has to do
with whether we keep minor changes to the TAP formatting as the new
default or replicate Test::Builder's current quirks.

This effects the upcoming Perl QA Hackathon and I have to make a
decision before Friday.

Replies here are ok, but I'd prefer replies on the Github issue please
to keep the discussion coherent.
