IIRC, one of the reasons for this was so the existing 8 but support
chips could be used. These were originally designed for the 8080 & 8085
and could be used with the 8088.

There would be no problem with the support chips, the IO, DMA and so on.
No, the issue was around the data bus. The 8086, and the 8080 couldn't drive the data bus, they needed the address latches and buffer drivers.
The incremental cost of the extra set of components for the 16-bit bus was what made the decision.

There is an irony to this. Semiconductor components have always had an aggressive pricing curve, both with quantity and time. By the time the IBM PC hit the showroom shelves the cost of those extra components meant that a fill 16-bit bus with an 8086 would have been cheaper than the 8-bit with 8088 at time the original costing was carried out.

The joke comparing automobiles to computers comes to mind.

At a recent computer exposition, Bill Gates reportedly compared
the computer industry with the auto industry and stated: "If
General Motors had kept up with the technology like the
computer industry has, we would all be driving $25.00 cars that
got 1,000 miles to the gallon."

but don't forget

How long did the whining go on when KDE2 went on KDE3?

The only universal constant is change. If a species can not adapt it
goes extinct. That's the law of the universe, adapt or die.
