Er... because XeTeX was created much later than the formers? Your
question as such doesn't make sense; it could be rephrased as "Why
haven't they disappeared?", and to that the answer is easy: because it
would do much more harm than good. There is no reason to willingly
break compatibility when keeping the earlier programmes costs (almost)
nothing -- especially true for free software.

Same answer. And you should be aware that the Type 1 format was one
of the foundations of OpenType; if it hadn't existed in the past,
OpenType simply wouldn't exist as it is today.
