I'm personally using wayland for more than 3 years on my work laptop (Intel card) and my home desktop (ATI/AMD with OSS driver) and even if there were transient issues at some point, everything is pretty stable now with 3.30 (the version that will be released with buster). Like Iain the main annoyance I have in my daily use is with the desktop/window sharing in firefox.
Wayland has been (re)made the default in debian back in July 2017 (beginning of the dev cycle for buster), I don't remember receiving any objections at the time. The question about using it by default was raised by Jonathan in Apr 2019, two months in the (soft) freeze, it was already quite late at that point IMHO to switch back. This makes me wonder, are there even people using GNOME in sid/testing? Are there people testing with the default settings or has everybody switch back to X11? Because we had a full development cycle and we didn't have a massive number of bugs being filled about this, how should we interpret that?
It's also important to note that we are not pioneer in this, Fedora is defaulting to GNOME Wayland since Fedora 25 (Nov 2016). Both RHEL 8 (just released and using GNOME 3.28, so one release lower) and SUSE Linux Enterprise Desktop 15 (released in end of June last year using GNOME 3.26) are also defaulting to GNOME Wayland.
We could indeed revert to X11 in a point release if things are going horribly wrong, some first step could be to put more information about this in the release notes. RHEL has https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/8.0_release_notes/index#desktop but I don't think that everything there applies to Debian
