End of last year they did release 6.0, so it looks like they're not hiding their releases for a year. You won't get the LTS fixes, for a year though.
For me, this means I have to stay on 5.15 until 6.2( because of location module) is one year released -- summer 2022.
Additionally, Qt changed its approach to bugfix commits to go to dev first and then get backported, so even if a distro is stuck on an older version branch in LTS mode, critical fixes will be available publically and can likely be backported manually.
Overall the change to the LTS support strategy isn't amazing, but it's impactful mainly to 5.15.x since it's LTS and the transition to Qt 6 will take some time. Once the transition is over I suspect it won't be a significant issue however.
So, if you report a bug in 6.2, then you'll get the bug fixes in 6.3, assuming the fix got into the dev trunk before the end of the 6.3 release window?
