Including mention of a /48 general acceptance seems to be without any 
logic or foundation.

No one needed 16 bits of deaggregation in IPv4, I can't see any reason why 
16 bits of deaggregation is needed, or in any way sensible in IPv6.

How about suggesting a /36, rather than turning IPv6 deaggregation into 
the same mess that IPv4 has become - except several orders of magnitude 
worse, since with v4 the most anyone can expect to deaggregate their /21 
is into /24s, growing their slots in the global BGP table 8x, whereas with 
v6 you're leading a /32 into /48 deaggregation, growing slots in the gobal 
BGP tables 65536x.

Routers won't cope for long with people dumping v6 /48s into the tables in 
the same way that v4 /24s get dumped into the tables.

"The operator community will ultimately decide" - is nonsense, commercial 
decisions rather than prudent technical decisions take over when it comes 
to whether to accept silly deaggregation, as a result several high profile 
content and network providers are no longer running default-free because 
of the sheer size of the tables no longer fitting on their equipment 
(which would have fit just fine if it wasn't for general acceptance of 
excessive deaggregation).
