He's in the MAINTAINERS file[0], and the person with the most commits in 2016-2026 period, so no.

The pdumper has been around for yonks, and afaik Zaretskii is still maintaining.

We should be so lucky. No, sadly, bruv has repeatedly enticed handing over the keys over a silly dustup like the portable dumper, the long line mishandling, or the c-ts-mode incident where he could not bring himself to admit wrongdoing, then invariably back out hoping no one will remember his tantrum. This emacs thing is really all he has.

Why would he resign over that? He's threatened to resign over removing DOS support, but has no problem with pdumper.
