That just isn't true, and this paper is proof: https://www.usenix.org/system/files/conference/usenixsecu... "In this section, we demonstrate the effectiveness of our re-
verse engineering effort by presenting microprograms that
successfully augment existing x86 instructions and add
foreign logic" "We see great potential for constructive applications of
microcode in COTS CPU s. We already discussed that
microcode combines many advantages for binary instru-
mentation, see Section 7.1. This could aid program trac-
ing, bug finding, tainting, and other applications of dy-
namic program analysis."
