Increment Berserk Games

Should berserking an increment game remove the increment?

Especially for lower time formats?
In a 5+2 game, if one person berserks, then the time format is

2.5+0
vs
5+2

I think that both halving the time and removing increments are big handicaps on their own. So I ask you, is removing the increment as well as halving time in berserk fair, or should the berserker get some form of compensation?

If you want fairness, don't berserk.
