I like the idea of a standardized way of conveying where the project exists on a spectrum of personal hobby to foundation. I'd personally imagine four levels:
Level 0: This code meets (met?) my personal needs. I'm pleased if you find it useful but do not expect a response to suggestions or bug reports.
Level 1: This tool has a solo maintainer. I'll do my best to incorporate suggestions that fit my vision and address bug reports with reproduction steps when I have free time.
Level 2: This project is maintained by a handful of like-minded contributors. Besides suggestions and bug reports, if you're interested in contributing, please join our discord/element/forum/listserv.
Level 3: This project is maintained by an organization. Before submitting a bug report, please read our wiki.
This is a late update but the site and docs make it extremely clear it's a level 0. ala here's a thing that may help you; I no longer use it either personally or professionally so adjust your expectations accordingly.
