But are there any other modes with here-docs?

I would do it like this:

a) defined a variable which keeps a function looking for a here-doc.

b) Merge your two adapters into one function (which makes a runtime
   dispatch basing on the mode - and croaks if the mode is not known);
   put the function into the variable.

c) delegate the other work to the mode writers - when a mode supports
   an interaction with your function, it should make your variable
   buffer-local, and will put its helper function into the variable.

Hope this helps,
