I think we're talking past each other a little.  I'm not talking about
changing the text content of a src block, I'm talking about modifying
the syntax table of a major mode such as sh-mode to ignore or handle
<<noweb>> syntax in an "edit-special" buffer.  That was my
interpretation of your suggestion of using fontification to solve this
issue.  And if that's the case, I foresee a lot of edge cases for
modifying the display of major modes.

This discussion is not about whether to allow users to modify noweb
syntax.  That feature is already a part of Org, well documented, and
utilized.  The feature request I'm making is to allow that modification
to be done on a per-block level.
