Yes, that's how release criteria usually work. It needs to be a general problem affecting everybody or a large part of the audience (best guesses applied here). We usually don't block on obscure setups, unless it has e.g. catastrophic consequences (severe data loss, etc).

Release criteria affect more things than just those which are important for LiveCD usage and/or can't be updated. For example, keyring functionality is not too much useful on LiveCD, it can be updated post-install, yet it has to work on the release day. The same goes for lot of apps which you're not likely to use from LiveCD, e.g. gnome-documents, gnome-contacts, etc.

But it's true that software which can be updated post-release gets lower severity when discussing the impact of the bugs (especially when it's not a general issue affecting everybody, but just a part of Fedora user base). The same would apply here, the point is not to block on obscure bugs but to block on widespread bugs.

I proposed this criterion because history shows that the approach you mention (let's fix it with updates) didn't really work, at least for GNOME. So I'm trying something else, to make sure it gets the attention I believe it deserves. (We reached the same conclusion during our blocker bug review). It seems that people opinions on importance of this feature vary wildly, which is unfortunate. If we don't reach consensus, it can't be a criterion.

A thing to consider - if we know user switching is completely broken (not just broken in some use cases or for someone, but completely broken), are we OK with releasing Fedora like that? Should that feature deserve a prominent position in the system/user menu, if we're not willing to guarantee at least basic correctness?

In that case we would probably need to specify an explicit exemption for user switching in . Please note the description box below the criterion where it says:
# The key question is "would this bug cause significant inconvenience or just a really bad first impression to a typical user or reviewer of the release?"
