There are breaking changes between these Ruby versions.
For most packages, upgrading Ruby and having the tests run would work, but I count 209 packages with tests disabled (I did not check how many of them run on 2.7).
Personally, I wouldn't want to risk it :)

Probably not, end of support for Ruby 2.6 was 2022-04-12. 
Fwiw, end of support for 2.7 was 2023-03-30. The 2.7 -> 3.0 migration was pretty big in the Ruby ecosystem, I wouldn't expect there to be a lot of open source applications running 2.7 any more. Having a quick look at (gnu packagages ruby), very few packages still depend on 2.7.
