Why use 1.2/1.2 when you can use 2.4/1.2 ? It makes no sense whatsoever. Reducing download so you can say your connection is symmetric?
In any case GPON is already in its way out, new deployments use XGS-PON which is 10/10

But either way it's irrelevant to the point that the technology can very well support symmetric speeds and offering symmetric doesn't "need a lot of "active" equipment and that drives the costs up." as the commenter I originally replied to claimed. Also evidenced by XGPON having the exact same amount of active equipment.
On the other hand, more than 300Mbps upload is quite ok even with heavy video conferencing and what not.
