I actually used to irritate the devs about that very thing quite a lot back when i was on-staff, even trying to organize something with less pressure (like a Newsletter) to augment the Year-End-Updates.
But in retrospect, i came to realize not only how impractical it was but also how unnecessary.
Reason being: Most, if not all, of the entire current Dev Team is readily available for questions 24/7 in IRC & Discord, as well as on these forums.

Bingo ^ , therein lies the main hurdle. RL time management.
We all have to remember that these are not paid SOE employees required by corporate to do 'Stratics live chats' periodically for PR. These are noble volunteers, working in their spare time. And 99% of that spare time is typically spent coding & testing.
Letting them work in peace seems to indeed be the best method for consistant progress.
