I am using two each of those in my product. An inverter/charger. It's
the perfect part and small size for what I needed !
Just for glue logic but is much better than what I would need to use.
It also runs on up to 5V so perfect for interface to my 3.3V proessor.

Big-thing ASICs they are not, their strength is glue-logic and external
dependency reduction, particularly with the analog comparators.

When I looked at the parts they really didn't have much capability. I think they are pretty cheap in quantity, so if they do what you want and you need to build a lot of units, these can be very useful parts. Just not on anything I've done lately.

There was the CMOS cookbook, now there's the GreenPAK cookbook:
<https://www.dialog-semiconductor.com/sites/default/files/the_greenpak_cookbook_3q2020_final.pdf>
An interesting feature is mentioned at the start of chapter 5. To
maintain a given mixed-signal array configuration after power-loss the
devices are the equivalent of OTP and will boot into that state. But if
the particular device has I2C you can create a table of differences
between configurations.
Once powered-up the device can also be reconfigured over I2C. It would
seem that if you have a uP with I2C also you can store that table in the
uP memory and actually re-write the array hardware configuration on the fly
