Upstream dev-libs/gjs-1.66 has already ported to spidermonkey:78 which no longer has Python-2.7 dependency. https://gitlab.gnome.org/GNOME/gjs/-/issues/329 Bring forward please. Related forum discussion: https://forums.gentoo.org/viewtopic-t-1119925-postdays-0-postorder-asc-start-25.html
Since 4weeks shown dev-libs/gjs-1.66.1 at https://gitlab.gnome.org/GNOME/gjs/-/tags I wish repo gnome-next will show it.
Was bumped to 1.66.1 with :78 support in commit: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=0e0632ef5d9f2f19633d8b2530464ae9de45023e
