I agree with you. Creating a new syntax is not a good idea.

However, in some way, ob-C has created a new syntax implicitly by
instantiating a new main in absence of such a function in the source
block.

So why not to extend this idea by allowing a user defined function to
parse the source block. The default function is clearly
org-babel-C-ensure-main-wrap.

We could create a new header :wrap which replaces :main and holds the user
defined function. It can take three values
nil, org-babel-C-ensure-main-wrap(default), or user-defined-function.

So, in this way user-defined-function holds my own syntax for my future presentation.

What do you think ?

Best
