Two types of futureproofing, a bit confusing.
All GLX platforms are designed to be raised to 14 inches above top of rail, to allow level boarding on Type 9 and Type 10 cars once the 7s and 8s are gone. (The folding doors on the older cars would hit the higher platforms.)
All (save already-long Lechmere) are being built to 225', sufficient for two-car Type 10 trains or three-car trains of current stock. They are also designed to be extended to 300'. That's unlikely to be needed, given that 225' is sufficient for the Type 10s; it may have been a decision made before it was firmly decided to have the Type 10s be longer than the current LRVs. I have some discussion about platform sizes in Appendix H of my thesis. My argument there is that 225' should be the standard platform size; anything longer will require some very difficult modifications at some older stations, while not providing any real benefit.
