"The P4 designers used the strategy of making the common
case fast."

Duh. And I suppose all the other processor engineers optimized ARPL?

EVERYONE optimizes for the common case.

Shifts & rotates are NOT that uncommon. The P4 suffers badly as a consequence of its design.

The P4 engineers screwed up and now their product is history. The fact is that they wanted to optimize shift/rotates but the Netburst core forced them not to do it. Just a poor design.
