Yes it is more likely to be applicable to other apps other than WMs, but I also have integration in mind. So what if you want to write a WM like a library that can be used by whatever runtime a user may choose. Not sure that is a good idea but it sure would not be very portable if a GC must be carried inside the library. Memory consumption is not the only issue here.

If you were making a general point and not about WMs in particular, why didn't you say that to begin with?
