Why create a workaround for this language deficiency rather than fixing it?

http://www.digitalmars.com/d/pretod.html#mixins
"Mixins create a scope, macros do not."
"Mixins automatically create unique identifiers as required using a standard 
algorithm, macros have to do it manually with kludgy token pasting."

This of course applies to template mixins.  But why not make these points 
apply to text mixins just the same?
