[development] Coding Standards / Hook_requirements

I've just taken another quick run through the Coding standards because of a module I looked at last night. The new module states right on its project page that it requires PHP 5 (as more and more modules are doing). Yet, in looking through the code, it does not include a hook_requirements. I propose adding to the Coding Standards: "Any module that has requirements over and above base Drupal standards (e.g. PHP 5 vs. 4.3.5 for D6) must include a hook_requirements implementation to verify and/or warn users of this requirement." Unfortunately, I don't think Coder would be able to check this. Nancy
