Just scanned the series quickly, but can't we simply add registrar.webcommand
and extensions.wraptable()?

I see the decorators defined in the registrar module as a sort of DSL or
macro, which is nice if the concept is clear and we have lots of boring
repetition. But monkey-patching isn't that simple. We sometimes have to
conditionalize it for example, and we'll lose the readability provided by
decorator syntax.
