Great write up, Phil! I think you highlighted the problem well and circled the solution well. It did bring up an interesting question for me too. You pointed out that the SL metasystem originally was designed around Kim’s identity laws but fell short in certain aspects. I’m curious if you’ve put any thought into how the new SSI metasystem may fall short and if any of these are areas we should try to keep in scope or at least leave extensions open for. Would this make sense or is it the case where we can’t see the problems until we’ve got the SSI metasystem and so we’ll be forced to create a new metasystem in a decade or two again?
