Best comment from another related thread (not from me):

So the libxml/libxslt unpaid volunteer maintainer wants to stop doing 'disclosure embargo' of reported security issues: https://gitlab.gnome.org/GNOME/libxml2/-/issues/913 Shortly after that, Google Chrome want to remove XSLT support.

Coincidence?

PS: Seems libxslt which is used by Blink has an (unpaid) maintainer but nothing going on there really, seems pretty unmaintained https://gitlab.gnome.org/GNOME/libxslt/-/commits/master?ref_...

PS2: Reminds me all of this https://xkcd.com/2347/ A shame that libxml and libxslt could not get more support while used everywhere. Thanks for all the hard work to the unpaid volunteers!
