It's inherent to how FPGAs work. Logic blocks are necessary but are kind of a heavyweight solution to emulate normal logic (and they'll result in a ton of extra silicon driving leakage up). Perf/Watt has always been interesting as well, It's a major concern for data centers (worse perf/Watt requires more cooling which drives costs up).
