when there are interested parties, jointly with them and the process is
played a bit by some copr repo or similar. Purely theoretical work is not
needed.

If some third party supplies 'java' as the $legacy jdk, and the user
installs a Fedora package built on $current jdk, which provider will win,
and what packages will break?

If the user uses alternatives to set the jdk (that applies here, right?)
any applications that need one version or the other could break?

I understand these are relatively ignorant questions, but if the aim is to
provide a path for someone to maintain older JDKs it seems better to offer
them guidelines and best practices instead of "you'd better be competent
enough to figure it out".  They might not think of all the potential
conflicts.
