That's not true, I know to wait for some responses before doing a
release of these kernels.

We have that, you aren't noticing them...

Yes, look at the responses to those messages from Guenter, Shuah, Jon,
kernel.ci, Red Hat testing, the Linaro testing teams, and a few other
testers that come and go over time.  Those list out all of the tests
that are being run, and the results of those tests.

I also get a number of private responses from different build systems
from companies that don't want to post in public, which is fine, I
understand the issues involved with that.

I would argue that the stable releases are better tested than Linus's
releases for that reason alone :)
