Say you want a 24-bit delta-sigma DAC on board.. AFAIK only the 8051
core is available in production quantity (at least two suppliers),
with ARM availability (one supplier) projected to be in 3rd quarter
2K004. There are other similar examples.

More generally, why in the world would you reject a competitively
priced 8051 from consideration in an application where it would be
appropriate? For example, the modern Philips 6mm x 6mm P89LPC932FHN.

Or an inexpensive OTP P87LPC760BDH (USD0.87 ea/reel from Avnet)
