Kernel command line switching (i.e. this patch) is fine for my use cases.

SELinux folks might want

-static int security_debug;
+static int security_debug = IS_ENABLED(CONFIG_SECURITY_SELINUX_DISABLE);

so that those who are using SELINUX=disabled in /etc/selinux/config won't
get oops upon boot by default. If "unlock the pool" were available,
SELINUX=enforcing users would be happy. Maybe two modes for rw/ro transition helps.

  oneway rw -> ro transition mode: can't be made rw again by calling "unlock the pool" API
  twoway rw <-> ro transition mode: can be made rw again by calling "unlock the pool" API
