Wow, I've been running OpenWRT for years and never heard of this, thanks. Although I suppose it does nothing to resolve config upgrade issues, right?

It does exactly as much as using `sysupgrade` with any other suitable image will or would do :) So yes, limitations apply - but for most users with a bunch of custom installed packages, this is enough of a game changer regardless.
