They probably wont break windower (and if they do, probably not for long)- and the old UI will still be available if the new one causes issues for you.

SE is never going to incorporate any kind of 3rd party program into their development- it is just never going to happen, especially considering the hacky nature of windower which hooks into and reads FFXI memory- That won't be useful to SE adding on to or modifying the actual UI.
