Thanks Shuah for the guidance.  Do they summarize your point properly?

1. Testing a new feature on simulated / virtualized environment alone is
not sufficient.

2. Pre-enablement of a new feature is not allowed.

3. Contributing code that supports a new feature shall wait until there
are multiple firmware implementations available for the testing.

I like clear guidance, but this may be challenging for emerging
features.
