Yes. This is the crux of the matter, the big question: "I'm not sure we should store this kind of data on Wikidata."

I disagree with "Point 2 and 3 are for the BLT community to solve." In the interest of transparency, Gerard, myself, and BLT came to and are coming to the Wikidata community for assistance in solving this problem. I'm exhaustedly saying we had previously received consensus (with the understanding that at some point a new property that was more ideal could be used).

The "squatting" on the property was because BLT had a problem and Gerard and I were trying to provide an automated solution using the semantic metadata held in Wikidata. It was also an experiment in integrating Wikidata into a Wikipedia project, as this is a common need for outreach projects. The solution was very effective and positive.

The two different list styles is because bulleted lists are easier for Wikipedians to edit and understand. During editathons/events and hectic periods of planning, it makes it easier to add items to the task list if it's a Wikipedia bulleted list. And then add the catalog tag to the Wikidata item, a Wikidata item that might need to be created as a result of that addition to the bulleted list. Listeria tables are there to automate the list for future use, and for the current editathon event. So the two lists are a workflow tool, which I think is okay, as they serve different needs, different end users.

I object to your use of the catalog property to link to something that is not a catalog. I don't see why my objection leads you to expect me to offer an alternative way to track your project. I am not responsible for your project and don't understand what it is. If you can't understand that then you should not probably not be editing Wikidata.
 To add to that. I see three things:
1. Using the wrong property ( catalog (P972) ). Solution -> move to another property, this depends on point 3
2. Notability of the people BLT. Solution -> Add more information and links to establish notability (or worse case, delete)
3. Using Wikidata as a shopping list for a Wikiproject. Have a discussion if we, the Wikidata community,  want that (point 1 might not be needed if the end result is don't want)

For the people like Jane and I, you're basically squatting the current catalog (P972) property. So we care most about point 1. Point 2 and 3 are for the BLT community to solve.

Point 3 is probably the hardest one. On https://en.wikipedia.org/wiki/Wikipedia:Meetup/Black_Lunch_Table/Lists_of_Articles I found the shopping lists for the BLT project. People seem to be in the hand curated list and in the Listeria list. Clicking around I found https://www.wikidata.org/wiki/Q20011585 which seems to indicate that you had a Black Lunch Table meetup on 9 december 2017 at " The 8th Floor" and judging from https://en.wikipedia.org/wiki/Wikipedia:Meetup/Black_Lunch_Table/Triangle_Jan_2018 that seems correct. At the bottom of this page is another Listeria shopping list based on this. I'm not sure we should store this kind of data on Wikidata.
