Just one editorial correction:  "coincides" always needs to be followed with "with".  Otherwise LGTM.

However, I spotted a different problem, but I'm too tired to fix it now.  I'll try to do so tomorrow, or at worst Friday morning UTC-4 time.  Basically, this SRFI still says that binary positions are always exact integers, whereas we changed SRFI 192 to say that they don't have to be.

I PR'ed a few minor changes.

- The arity of close and flush procedures weren't specified. Made it clear that they take no arguments.
- Clarify that the "position" returned by get-position conincides the position next read! and/or write! performs the action.
- get-position of make-custom-textual-output-port said an exact integer, which should be an implementation-defined object.

Unless someone requests otherwise, I will publish a new draft with this language in it tomorrow (by pulling from your repo), then wait until Thursday (PT) before finalizing. 

I published the new draft without waiting, but I'll wait until Thursday before finalizing.
