That's a good point. When MCA was released everyone in the industry
agreed that the ISA bus was inadequate. EISA wasn't much better and it had
no more compatibility than MCA (systems were produced with both ISA and MCA
buses). The result was that neither EISA nor MCA succeeded and many of the
motherboard companies produced their own proprietary busses instead.
PCI now runs at half the speed of the motherboard bus (and PCI 2.1 can
run at 66MHz which is the same speed as the motherboard bus). The PCI
design supports multiple buses, RS/6000 systems have been built with 2
buses for double the bandwidth. There never were machines with more than 1
ISA bus, and when EISA/MCA were introduced ISA was considerably less than
half the required speed.

I think that we can just ignore I2O and let it go the way of MCA.

In return for "mailbag contention" errors from buggy Exchange
servers I'll set my mail server to refuse mail from your domain.
The same response applies when a message to a postmaster
account bounces.
