I already planned to donate to Thane before this agenda was written up. I haven't taken the time to fully understand this agenda. But based on the first post, I roughly agree with the comments on the post from Steven and Rohin, and I also left my own comment mentioning that going for some pivotal act directly might be easier.
If Thane sees some avenue of making this work, that feels alive to them, I think it makes sense for them to pursue, though (with the caveat of fork risks). Ambitious projects are great for learning.
