I think this was addressed in the discussion, with the solution to get
normal IPv6 space from the usual sources for thoses services. For
example the K root nameserver does not sit on the LINX exchange
network itself, but in a very different netblock, and this model could
be applied to IPv6, too.

If an IXP insists on putting those services on the same net, they can
of course do so if they get routable IPv6 space for it, through
standard procedures. Use of those addresses for IXPs is in no way
forced.

I'd pragmatically say the need came up for addresses for this usage,
so it had to be defined somehow, in order not to create a source for
arbitrary non-routable globally-unique IPv6 addresses.

Well, it can be discussed endlessly what the "right" definition is.  I
wouldn't mind if some "transit ISPs POPs" fit this definition if
people peer there (as opposed to just getting transit).

So they next question will be what "peering" is, but please, no ...

Yes, why not? It's not externally visible through which LIR the
request was made.
