No, I don't think it really makes sense to change the status of stalled PRs.
We have 156 open PRs, 56 are mine
My guess would be that we would have to convert a large majority (100+) of the existing PRs, and that just creates noise.
For example, in the last half year I worked another round on several PRs that I had opened in 2015. Several are now stalled again until I get out of the statsmodels.distribution topic.
Beta-regression has been stalled for a long time, but I just looked at it several times again as example for new classes of multiple link models, which will be coming "really soon".
What I have done in the opposite direction is to add label `prio-elev`, elevated priority, to issues or PRs that we should look at soonish.
I changed my work style and look at issues and PRs almost only
by topic, except for higher priority and urgent ones.
