My assumption was just from, afaict, the general lack of triage on GitHub issues, i.e. for a few needs we have like tracing/APM, and then also admittedly esoteric topics like this stack trace fixing:

Fwiw I definitely sympathize with issue triage being time-consuming/sometimes a pita, i.e. where a nontrivial/majority of issues are from well-meaning but maybe naive users asking for free support/filing incorrect/distracting issues.
I don't have an answer, but just saying that's where my impression came from.
Thanks for replying!
