overwrite-mode cursor:
  - this wheel has been invented elsewhere and has been in wide use in
  many editors for a long time.
  - bad things happen if you don't notice that you've accidentally
  pressed "Insert" and continue typing. A visual clue is an extra aid
  for the user.

read-only-mode cursor:
  - I am not familiar with a similar feature elsewhere.
  - The fact that you can't input text is a good enough indication that
  the buffer if read-only. Changing the cursor in this case needs added
  code and documentation.   _I_ can see no benefit to the users from this.
