Hm, why are people euphoric about BIP100 superseding BIP101?
AFAIK, there is no implementation yet of BIP100, and its details are not even fully specified. (Is there one?)
For me this shows the level of chaos that's present in this ecosystem. Luckily this is a very fast and innovative system and things will improve faster and better than in other systems. This is the first attempt of the ecosystem to learn and reach consensus. It needs time to learn how to deal with these situations. But for now there is chaos.
Because BIP101 is broken.
Why?
