Will there soon be an option to play on non-x-wrapping maps (are you (or
someone) working on it)?

Non-x-wrapping maps would require that the first and last columns are
never explored and forbidden to enter, and only exist to allow the
client to render the terrain correctly. (Like the T_UNKNOWN thing.)

And there should be a client option to play on a map just like the one
used now but with the poles on the sides and the wrap top-bottom. That
view is just as valid as the current one. And compatible.
