There is a significant amount of Phabricator dark matter out there - companies/people using the software, it works well enough, not really easy to know they exist or anything about their usage. I'm sure at least some of them have moved to Phorge. Automattic/wordpress.com have moved to Phorge and I wasn't even aware that they were using Phabricator before that. This is despite the fact that I did a pretty extensive amount of research to identify every company using Phabricator back in ~2019 as part of my work for Wikimedia, with the goal of reaching out and trying to organize an informal Phabricator users group. We had the idea that the various corporate users probably had good reasons to be collaborating and at least talking to each other since most of them were not active in the upstream project. Anyway, that never really panned out, although it did trigger a flurry of interest and some ongoing discussions via email (maybe even one video meeting but I can't remember the details now.)

Abandoning in favor of T15890 and D25774 per previous discussion

I think that is complex because some admins are not well active on their platforms, so as said before it can be underdimensioned

I'm not skilled enough to look into the bigger picture, however maybe the Edit Column dialog could have a third field apart from Name and Point Limit to also have Task Limit (or Card Limit?). Point Limit and Task Limit then must be mutually exclusive (do not allow to set both for a column, or even...board?), somehow.
