Are these still only available from the "boutique" distributors? I'll
buy from them but I'd prefer to buy from Digikey, Mouser or Arrow or
other large mainstream distributor if I can. Will they ever pick up
these lines, or is the total expected sales quantity just too small,
or what? Digikey and Mouser carry lots of Adafruit and Sparkfun stuff,
I've ordered the breakout boards for several hard-to-hand-solder
chips, they're a great convenience. If the big distributors can carry
those, I would think they could carry the synth chips.

There's a company in Singapore who will strip off each layer of an IC and generate new masks but also an accurate schematic of the IC so you can make an exact clone or an improved version should you so wish.  But they can only give you an estimate of deposition times and so you need to run a full trial and errors runs to get that right.
