Indeed, it still is.  But there are many choices and in the end it would
depend if you wish to use boards native to that bus.  If you not using
board native to the bus then there is no compelling reason other than 
convenience in seeking protocards and connectors.

In the past I've used PC XT (ISA-8) bus as it's 8bit data/20bit address
and enough pins for anything. the convenice was there are/were bare 
busses (or you can cut up an old mainboard) and protoboards were cheap
and fairly large.
