I expect JDK users would disagree with you. JDKs from other vendors
(Amazon, Azul, Oracle, etc.) are built in exactly this way. We (and
likely other GNU/Linux distributions) are the exception here.

It's not a trademark issue [0], but one of user confidence in what is
being provided. The "OpenJDK" name can be used as long as it's OpenJDK
code that is being built, and not, say, the OpenJDK libraries combined
with a non-OpenJDK virtual machine.

I think the alternative would be that we reduced testing in a similar way
e.g. only run the TCK on the latest released Fedora for each JDK.
