I'm for leaving it out permanently unless there is a strong reason to
put it in. JDK-8248505 was found late in the last 11u release cycle
and we had to respin the release for it. Your mail suggests two
further changes are needed since that.

As you say, this patch makes changes to the provider system. As far as
I'm aware, this is not a bug fix, but a performance enhancement, which
then broke third-party providers. I don't think something like that
should go into a stable release like 8u unless there is a very good
reason.

That the original fix first went into 12u, but issues were only hit
much later when it was backported to 11u, suggests a general problem
with changes in the new short term releases not being widely
tested. We should keep that in mind for all future backports.
