Sounds reasonable; I'll have a look at it.

I think that we discussed (some of) that before in the comment section of
another issue: JDK-8267690. You might want to re-read it.
What this PR proposes is to apply a band-aid until we're ready to treat the
issue properly. The treatment you are suggesting is proper, but heavyweight in
terms of the process: it involves an API change, which requires a CSR.
