The most significant problem with window resizing is not the terminal
itself, but window/session managers that try to do "live update" of
the window contents as the cursor is rapidly dragged around.  These
tend to send a stream of WINCH signals which we have had to do various
tricks to manage.  I would be concerned that attempting to write a
control sequence to the terminal and read back the response in the
midst of a flood of such signals would fail as often as it succeeds.
If this is already limited/controlled by the mechanisms in place,

(not text/x-something), without base64 encoding if possible.
