It's related. If you want decent performance with pipelining, you're going to want to speculate at least a bit -- assume that FP math doesn't trigger exceptions, assume that you predicted branches correctly, assume that memory accesses don't fault, etc. Intel does more speculation, but you won't find anything beyond the tiniest embedded CPUs which don't do any.
