Why did you said that "The page_referenced() path will only cover the ""_text_"" section" ?
Could you elaborate please ?
I was under the wild assumption that only the _text_ section will be
PROT_EXEC mapped. No?
Yes. I support your idea.

Why do PROT_EXEC mapped segments deserve special treatment? What about the
other memory segments of the process? Essentials like stack, heap and
data segments of the libraries?

Christopher, please look at what changed in the VM
since 2.6.29 and you will understand how the stack,
heap and data segments already get special treatment.

Please stop pretending you're an idiot.
