IDE stood stale for a year while you vanished (to CERN ?) so the rest of
the world decided to get on with it. As it happens an evolutionary change
would have made no sense as the mentality of the code is [thankfully]
quite different and we could eject an enormous amount of crud in the
process.

Its mostly happened, there are some interactions that still slowly push
their way up into the block layer.

Yeah - I'm slowly working on it in parallel with the tty code.
Unfortunately the big remaining one (mac support) didn't happen as the
Mac that dwmw2 loaned me died and as in typical crapple design style it
needed major surgery with sharpened wall paper scrapers to even open it
the work didn't get done.

For non mainstream systems I'm in no great hurry to move them to libata,
its not like a Commode Amiga is a serious platform that needs the latest
cutting edge code.
