If you are trying to demonstrate or teach peerings across multiple ASNs and show examples of how multiple ISPs might carve up their /32s (or larger) differently, it's very hard to do all of that within a single /32. Antonio and I do very similar types of training from the sounds of it and we have encountered the same issues. A larger doc prefix would be useful. I don't see it as critical, but I don't see any significant reason not to do so. I understand the objection raised by Cameron, but, really, anything the IETF does likely creates some amount of work for operators. Thus is the nature of operating a network built on an evolving technology. You knew the job was dangerous when you took it.

I might, for example, need to use layers of prefixes like > 2001:db8::/32 > 2001:db8:100::/40 > 2001:db8:202::/48 > 2001:db8:300:300::/56 > 2001:db8:400:440::/60 > 2001:db8:400:444::/64 > but I seem to have plenty of layers at my disposal.
