Don't really see it as compromising, unless I really want that 1t jump between each cog like you get on the 11 speed 11-23 cog.
I've been riding predominary on 46t with a 11-28 for ages, it's only when it ramp up over 15% I drop to the 34t chainring, so the majority of time, the 34t see very little action, with the exception of the Pyrenees on a loaded touring bike.
Even with a 34t chainring, it give me the same GI as 40/36.
