I'm not sure that's breaking that convention - the call chain is in  
vcc_regexp and it's a test before generating the C for the compiled  
vcl binary. Maybe I'm misunderstanding what you mean by "compiled  
code" in this case - I think that you mean that any generated C from  
vcl should only call VRT_* functions, which this patch doesn't change,  
as it's a validity check before code generation occurs.

I looked on http://varnish.projects.linpro.no/wiki/DeveloperResources  
but didn't see a mention of this convention - is there another place I  
should be looking so that I can understand the coding conventions of  
the project?
