And how to distinguish which files you want read only and which you
don't. This doesn't look to me like a very useful features. 

Would it be feasible to redirect source references to original org file?

Something of that kind now works with org's C-c '. If you evaluated
functions in org edit buffer. You will be redirected to original org
file on errors or debug. It doesn't work with org's C-c C-c as yet, but
I am looking into it.

There is visit-file-hook. You can add to it a simple function that
checks for a file name and marks buffer read only.
