I'll bite.
Seems like you were trying to link to this. Feasts seem like a weird topic to be worked up over, but the existence of feasts in Warband indicated that Taleworlds kept Lord to Lord relations in consideration. Feasts existed as a vessel for the AI could regain relation with each other. Roll your eyes and be as pretentious as you want, but their departure from Bannerlord indicates that Taleworlds is cutting corners and no longer caring about this, ultimately reducing the depth and immersion. Indeed, with the ruler clans hoarding fiefs so much up until this patch and constantly acting against the majority, that there is nothing even resembling Lord to Lord relations present is obvious.
EDIT: That you've flippantly disregarded a well-constructed, comprehensive list of missing content that affects other players merely because one item seemed minor speaks volumes about your interest to even engage in a genuine discussion.
