Exactly, especially when the limiting made no sense in the first place.
I thought one of the most hilarious moments of the series was when they went into "grey mode."
They don't have enough deuterium to keep the engines going, so they cut the lights & heat off as if that's going to save energy. Give me a bandaid, my arm's been ripped off.
The energy needed to replicate a cup of coffee or to keep life support on in a crewquarters is probably an infinitesimal fraction of the energy needed for the ship to go half impulse for five seconds.
