But for the packages that explicitly need to pull in openjdk:

  git grep 'openjdk[1-9]' | grep -v define-public | grep -v java.scm | nl

     2  gnu/packages/apl.scm:    (inputs (list bash-minimal openjdk18))
     3  gnu/packages/apl.scm:    (native-inputs (list `(,openjdk18 "jdk") zip))
     4  gnu/packages/axoloti.scm:     `(("openjdk" ,openjdk11 "jdk")
     5  gnu/packages/bioconductor.scm:     (list (list openjdk11 "jdk")

It is not a crazy number of packages, but in cases like diffoscope and
enjarify, which seem fairly compatible with arbitrary versions, it would
be nice to have an unversioned option to specify?

Maybe I confused things by talking about the "default" version, I guess
I was wondering if it would make sense for an "openjdk-latest" or
"openjdk-lts" or whatever color you want, just as long as it does not
require specifying (and more importantly, keeping track of) the version
of openjdk needed.

live well,
