6.0.0 was released 08.12.2020, with 6.0.4 released at 04.05.2021 as the last patch release in that minor series. That's more than 5 days of support for the 6.0 minor series.

If Debian supports its releases for longer than the upstream projects do, then that's a (perfectly valid) choice of Debian, but I'm assuming that involves maintaining those projects as well, to the standards of Debian's support policies.
