If they already make those - sure.
If not, I think satisfying our curiosity would likely be a huge waste of their resources.
The point of roadmaps is usually communicate plans to partners/investors, so they can make appropriate decisions.
Idk how big gg.deals is and if they have those external investors and partners that need to know their plans, but if not they would be wasting their resources making roadmaps.
For those who never participated in making of one:
Roadmaps require a plan months/years into future to know what will be worked on. Producing such plans requires preliminary analysis of things that may or may not be worked on, setting priorities on those things and then editorializing that info to be short and concise. That's A LOT of work, that might be wasted if 2 if they change direction 2 months in. Also, roadmaps are like a promise - they take commitment and makes them less flexible.
