No, it would still load anything built after the change. On the other

No, he's really complaining about the lack of granularity available.
If struct tty changes, then a kernel version bump would be needed (some
LKMs may care about that -in fact, it is quite likely) - but that
will mean all LKM's fail to load (normally), even (say) an LKM for an
ethernet driver, which wouldn't go anywhere near struct tty.
Slightly finer granularity would probably appease most people. Personally,
I don't care, my kernels don't include "options LKM" ...
