Ok, glad to know I didn't misrepresent anything :-)

Sure, we recognize that. You use of stockjdk11u in the gate is a great
help. As for native image, Red Hat expects to be ramping up testing on
OpenJDK jdk11u now that we are able to use it. So we should be able to
catch issues and hopefully either suggest fixes them or, at least,
report them back to you upstream in a timely fashion.

Yes of course and we appreciate that effort.
