I see what you mean. We have some discussions around this quite often. I myself am also not to sure where all of this will lead us. Strange times. On one hand it is fascinating and on the other site, looking at environment, copyright and other topics I have no answers to important questions...
I've been a team lead in software delivery for 15+ years at an agency. The "solo project" path started differently for me: I built an internal tool because the existing options didn't solve my problem. Measuring flow metrics from Jira turned out to be something other teams wanted too.
What helped: solving my own problem first, open sourcing it, and writing about the domain (flow metrics, delivery performance) rather than the tool itself.
