This draft attempts to retrofit semantics into various bits in that field. I can see why it's tempting to attempt this, but it introduces a significant degree of interpretation semantics and, more importantly, backwards incompatibility. At the time when we were still discussing draft-heitz-idr-large-community, the issue of future flexibility and semantic interpretation was extensively discussed, and the consensus of the authors + working group was that it was more important to get a draft out there which implemented "deployed + simple" rather than going for a slightly more complex design which would have allowed future extensibility. The opportunity to use a more flexible structure was not taken at the time, for good reasons, and we knew at the time what those long term consequences of those decisions would be. Retrofitting this complexity into rfc8092 reopens these arguments, but from the point of view of watching the ship after it's sailing past the horizon. If we need a better asn32-compatible extended community, then we should define a better, asn32-compatible extended community and do the job properly. We should not try to claim that rfc8092 provides an appropriate framework for this, because it doesn't and because if we try to bend LCs in this way, it will leave us with a legacy of perpetual dysfunction.
