I've assumed that, and personally I would hate that, too. A forced low/ pixelated resolution can be okay or at least for a while, but as a player I would demand to have the option to switch to my desktop resolution when I'm sick of the pixelated look.
As I've stated before I tried to go a similar approach but was not sure what kind of effects I want to implement into the game from a perspective of consistency, esp. such stuff as modern looking water shaders or similar or post-processing effects.
