I mean, after a decade of Bethesda being really poor on the official post-launch support of their games, at this point the surprise would have been a patch which really tries to address a massive number of issues.
Of course not blaming the devs at all here, for this is totally an exec decision to leave the games barely supported and put all the polishing work on the modding community.
