Yeah, I was puzzled as well, but didn’t press it because I figured that as this has some aspects of 451 overlapped with mine, that it couldn’t be approved. I could have revised it to remove the overlaps, but felt that 451 would go up before mine anyway; and thus I decided to see if Lost would consider my additions in the interest of time.
Lost didn’t reject it, btw. It was @Chris.Admin
"Thank you for your AIP submission. As many of these proposed tenets have already been suggested by AIP-451, this Idea was rejected based upon Guideline #4 of AIP-1"
I am still puzzled as to why an idea would be rejected even though it doesn’t conflict with a passed AIP - which 451 isn’t. I looked at AIP-1 and didn’t find the answer there because it seems to apply to passed AIP and not ideas. If we applied the rule to ideas under discussion, then as you said, that means we can’t have or discuss similar ideas even though they aren’t passed AIPs. Hopefully the @Facilitators can shed some light here.
