HI, First, regarding community size and activity, while growth has been slow, the project has maintained a functioning community, produced releases, and addressed user needs. Not all ASF projects grow at the same pace, and some fill niche roles. Note that the project primarily exists to produce training materials, not software releases, and it has produced over 20 presentations on various ASF topics and projects.
To judge if this is a viable TLP, it depends on whether the project demonstrates enough independence, process maturity, and community self-governance to stand on its own. I don't think any of this is in question. Kind Regards, Justin
