I really want to highlight this part.

There are no IMA tests I'm aware of (outside of builds with CONFIG_IMA=y).

For that matter, we only see a minority of subsystems actually testing stable
releases.

This is something we've been working to improve for a while, but we're quite
far from that goal.

Sadly your vibes are somewhat grounded in reality.

This is not, and I appreciate the feedback. Thank you.
