Ravenous Bugblatter Beast of Traal
In thinking about it, I think 5e would need to take a few steps back before taking a step forward and incorporating large PCs.
Consider ogre & giant damage. That's way too high for PC-level at-will attacks, per class buff. But D&D has the options of increasing number of attacks or damage done as a way of increasing weapon threat, and growing larger doesn't scream out "give me 4 attacks that are each only as powerful as a medium creature". So foes have greatly increase weapon damage because foes have CR appropriate damage. But having a large sized PC that defeated an Oni and saying "their glaive does 2d10 before strength" breaks.
If the damage was something like 13th Age, where there are no default extra attacks but weapon damage die is set by class and weapon damage is [level]dX could handle it. Because 3d10+STR by a 3rd level fighter or 3d10+STR by a large sized creature that an equal challenge to a 3rd level fighter are, well, the same.
But that doesn't work well with casters and other non-weapon wielders. If you want to play the minotaur warlock, you should without shooting yourself in the foot.
