Is your roadmap is already finished?
Or it could be changed in the near future?
If course the plans of the team could be changed, so its possible
However not too much, cause this roadmap is like promise from the devs to the investors
If it will be changed a lot, then trust of the investors will be lost
Yep, big changes are not that great, but if they are justified it shows that the project can survive even under hard times and adapt to the situation
