You mean,
"because auf zhe place und raute effort I dont knov whezzer".. ;-)

Seriously though: the FPGA is great because you can reconfigure it
when you need.. It would be nice to be able to have that need more
often than once per boot. You could even think of a reduced
instruction set CPU which sets up pipelines for additional
instructions as and when they are needed - substantially removing the
die size needed, while still giving you the whole range of
capabilities..
