I think it is because nostackframe is a directive for the declaration of 
the function itself, to tell the stackframe generating code to skip the 
stackframe. That is also why it is linked to assembler; directive, since 
with assembler the compiler can't auto determine to generate a stack frame.

It has no relevance to the calling code, so it has no business in a 
procedural type declaration.

Maybe take a step back and try to describe what you want to achieve.
