As long time programmer that has gotten into modding Bannerlord lately, if their limitations with automated testing is anything close to the outright impossibility of testing that mods have, I imagine that their deployment/releases are nightmarish to say the least which would prevent them from ever commiting to a release window or cadence.
Also, after playing around with the Dialog and Quest system I have come to understand why roleplaying content is so sparse in the game...
A lot of the engine stuff seems top notch, but the Campaign System was clearly not worked by their top people.
