On a more practical note, is there a dedicated maintainer for jsonrpc?
I lazily assumed it was João but now see Daniel Pettersson's name in MAINTAINERS (CC:ed).
Yes, I've handed over maintainership a a while ago. Good call Cc'ing him.
If there isn't one, or (perhaps equivalently) the answer is the collective of interested Emacs devs with particular weight given to past jsonrpc contributors, then I'll just make a more polished patch, test some more, and push if there are no objections.
Sounds like a plan.
