Because it is in ISO/IEC 8859. Hadn't ISO/IEC 8859-1 been so
commonly supported, MICRO SIGN would have been canonically
equivalent with GREEK SMALL LETTER MU.

That's a mistake. It should be in the Greek script, of course,
just like the OHM SIGN (which is canonically equivalent with
GREEK CAPITAL OMEGA; the latter of course the preferred
character to denote the ohm unit symbol, just like GREEK SMALL
LETTER MU is the preferred character for denoting the
micro unit prefix symbol).
B.t.w. the OHM SIGN comes from ISO/IEC 6937.
