It is not Liam’s job to make sure the rules are enforced on the server. If somebody wants such a mod written, write it yourself and either MasterP or Liam can upload it.
Seriously guys these are such small things; live with it or devise your own solutions. No reason Liam should have to spend his time coding plugins for things that aren’t even broken. If your question is about the rules as they stand, that is something for MasterP to decide.
