It's great to have the PIO in a smaller/cheaper device, but if that is the kind of thing that you really like, I do want to mention the BeagleBone SPUs and the Parallax Propeller / Propeller2 are similar/more powerful implementations of this concept.

RE: Propeller2- at $10+/chip, I'm just going with an XC7A35T or the TI AM243X (actually less $ and substantially more RAM) or AM62X series CPUs.

33000 LUTs and 90 DSP48s are more than enough to do 10+ RISC-V cores, I don't understand the niche this product fills.
