Absolutely, this is why I think discussing this would be very healthy.

- first to clarify what the consumers of your branch are expecting it to
be
- then making clear what your understanding of "stable" is
- then clarifying whether the stable branch is there for you or for its
consumers :)
- finally finding some intersection (some time in the future :) ) that'll
suit all parties

"Everyone is reviewing everything" is not my understanding of scalability;
hence my proposals.
