I agree, but this is not what I meant.
If you want to get second /48 prefix to test e.g. multihoming, you can
contact nearby IPv6 sites directly. 6Bone DB gives very good info on
this.
If you want to get direct connection to an interesting service, so that
the traffic will not flow through your own IPv6 upstream, you contact that
particular destination directly for private peering.
Etc.
Only good I can see for asking for peers _here_ is to enhance "global"
connectivity of a pTLA. As there are filtering rules in place, /48 sites
should not have need for this.
Ie: I'm not saying private peering should not be done; quite the contrary.
I _am_ questioning the objectives of asking for peers _here_ for
non-/{24,28,35}.
