but with 1.20 out and stable, and semantic bundle about to not care about mw 1.17
Please understand that SMW+ extensions have many interfaces to both MW and SMW. Sure there'll be those that work with MW 1.18+ also, but I think it's important for our present goals to be focused on MW LTS version, with express understanding that all SMW+ extensions must work with the most recent, and all legacy, SMW versions.
I'm not bothered by SemBundle's policy that its deployment is without regard to MW LTS, but I'd be a bit surprised to hear that it'll reach a point that it can't be installed on MW 1.17.
