Yup. And most of these customizations are aiming to solve the
fontification problem. If we did not have the problem to start with,
re-defining the noweb wrap syntax would be unnecessary in many cases.

Org mode does not _currently_ modify the code. But that's actually wrong
- things like escaped ,* or indentation sometimes also stay on the way
and produce incorrect fontification. So, rewriting the fontification of
src blocks to cleanup the code before fontification is long due.
noweb references is just another manifestation of this problem.

I am not in favor of adding features that aim to serve as workarounds to
Org mode.
