I found such a case in ses.el. However, I am not sure if much can be
done mode-specifically in such scenario. Major modes using a custom
function may set the value of `major-mode' anywhere down to right before
`run-mode-hooks' call.

The only universal option then is indeed your suggestion about permanent
local variables. They were overridden by hack-local-variables in the
past anyway.

What can be probably done is a call to `hack-local-variables' inside
`kill-all-local-variables', but setting only the variables marked
'permanent-local. The later call to `hack-local-variables' inside
`run-mode-hooks' may then only go through the remaining variables.

WDYT?
