Copying from the other thread that was closed:
I think this proposal needs to address how it relates to SAC_scale. Does it replace it or is it supposed to live with it? I can imagine it is better if it replaced it, but I am not sold on the idea of them living together indefinitely. If there is a roadmap to eventually convert sac_scale to this (or provide specific guidance when both are to be used), then I think it is indeed interesting and would cautiously support it. I can understand that SAC feels Europe-centric.
Also, I am shamelessly plugging this: Adding T0/strolling to sac_scale
