   ...Is this running extra micro code to fix some hardware bug/unreliability? How can this happen? Doesn't look like a normal design decision.

      It's to satisfy IEEE 754 and it's been this way for decades.

         I don't know who is down voting you. AFAIK IEEE 754:2008 does require support for subnormals. You can optionally have modes that flush them to zero, but you must support subnormals.

         I haven't done any work on this stuff since 2019, so my memory may be hazy.
