It wouldn't help, if you look closely, you'll notice that in the "other
releases" section you have the most recent version of each of them. That
does not preclude the existence of the branch earlier. For example gcc-9
was released in 2019 and 9.5 was emitted 3 years later. That's quite an
amplitude that doesn't help.
