This is really going from bad to worse.  But I can't say I'm
surprised.

Eli suggested to keep the behavior backward-compatible, rather
than ensuring that the return value is a string.  That is a
reasonable approach.  It's OK by me.

It is the 2nd of the 3 approaches I described as reasonable 
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=21391#52):

d> 2. Make `thing-at-point', as before, return just what the
      firat `if' clause returns, if that clause is taken.
      IOW, move the removal of text properties (from non-nil
      NO-PROPERTIES) into the second `if' clause.

Can we please just do that, and stop f__ing with thingatpt?

I also suggested that we do this, in that case:

d> Point out, in the doc, that `t-a-p', like `form-at-point'
   and its callers, can return a Lisp THING of any kind OR a
   string naming such a THING, and that the former case is
   realized via property `thing-at-point' on the THING-argument
   symbol.

That's important.  The use of symbol property `thing-at-point'
is one of the most important features of library `thingatpt.el'.
Pointing out `thing-at-point' in the doc without pointing out
this feature is letting users down.

Each of the 3 approaches I described is reasonable.  What is
not so reasonable are the kinds of changes you are suggesting
now.

If you are really entertaining removing existing functionality
then I would suggest you remove (deprecate) the NO-PROPERTIES
argument that was added fairly recently.  It is unnecessary,
and its addition was apparently completely gratuitous.
Did that action correspond to a bug fix or a user request?
I cannot imagine that it did.

Are we going to start adding a NO-PROPERTIES arg to _every_
function that can return a string?  If not, why does it make
sense here?  How hard is it to remove the properties of a
string?
