This scuttlebutt is misdirection. No GA browser has release support for the inert attribute, which sits behind an experimental feature flag for both Chrome and FF. The inert subtree work is ongoing, and notably, inert support is not showing as a release blocker. Yes, it'll be great to have, but it's far from mandatory. The significant outstanding blocker for FF is re. focus twiddling for better a11y, per recent discussion at whatwg/html#5678, c.f. bugzilla#1660271 & #1701230, and this is hardly boiling-the-oceans stuff. I'm excited for <dialog>, it's a survivor, and a great simplifier - particularly of dev conversations - and I recommend it (even with interim polyfill) to all and sundry.
