In the active thread "[VOTE] Retire HTrace from Incubation" Christopher Tubbs brought up the idea to make HTrace a subproject of an existing TLP. This would mitigate the issues of the community being inactive and the core instrumentation library not requiring ongoing development. It's a choice we could make now (assuming we were able to find a TLP willing to adopt HTrace as a subproject), or we could allow HTrace to retire and then revisit the subproject idea at a future time if someone becomes interested in patching and releasing a new version of HTrace.
So far, the people who have expressed interest in being involved with HTrace as a possible subproject are Christopher, Masatake, and myself. Is anyone else in the community interested in this idea?
