If the probable modders are counted in hundreds the players are nowadays counted in tens of thousands.
...And has it never occured to you why the community currently looks like that?
The current modding system is practically never getting updated, unfriendly, unwieldy, awfully incomplete, disregarded and just... not good.
No wonder the mod-liking part of the playerbase is being continously deterred from modding URW. I'd say it's impressive that BAC was ever implemented and maintained for so long despite seemingly zero effort from the base game dev cycle towards its general feasibility.
I never used BAC, I don't like it. However there are numerous mods I would most certainly use, if not for the fact that this game doesn't support them at all, and therefore nobody could've ever implemented them if they wanted.
Please reconsider the priority you assign to this overarching problem. So many games thrive largely thanks to their modding communities, and I don't just mean modern games, I also mean old classic games made eternal (like
Heroes of Might and Magic III, or
Gothic II, or old Infinity Engine games).
I don't see what could possibly be a downside of giving player more tools so that they can develop more content for your game that you perhaps don't have time to add or didn't come up with so far.
(Unless you literally don't want them to. Which would be fair, but for me personally pretty sad.)
