If you're talking about cvarx or zBlock type plugins, I'm sure they are aware of how to test for it, even though the value of cl_restrict_server_commands can't be checked from the server like other cvars. If a plugin is locking cvars like those, they need to update it to kick if players are using cl_restrict_server_commands 1.

This plugin is intended to change the cvar for the clients automatically so they don't have to go into the console (if they even have it enabled). Cvar blocking/locking plugins that aren't updated kick before this plugin can run its changes, so they need to be updated anyway for the Source engine update.
