Sounds great if they can really make it work.

Actually, for the simple-minded use I would have, none of what you say is an issue.If you want year 2000 process technology after you've spent many thousands on schematic, layout, simulation and then share that design on-chip with multiple projects from others on one die it might work for you.
Yes, it would be rare as almost every conceivable simple circuit already has a GP chip or programmable device already. This could be useful if you need to highly optimize a function like an image sensor or detector for a specific function.Actually, for the simple-minded use I would have, none of what you say is an issue.
But... That is a somewhat rare case, I suspect.
For my application, I looked at using a 6-pin PIC. I would cost as much to program it as the part costs.Yes, it would be rare as almost every conceivable simple circuit already has a GP chip or programmable device already.
Hard to see how a custom chip could ever be cheaper than a standard production run of a 6-pin PIC from a several billion dollar fab optimized for mass production.For my application, I looked at using a 6-pin PIC. I would cost as much to program it as the part costs.
The Itsy-Chipsy cost would probably be too high for volume production.
