    * Multicast routing has been improved by adding a scope field to the
      multicast addresses.

That means scope_id has two meanings

- link_local : on wich interface an packet go that can not determined by 
routing decission
- site_local : are also stored in multicast IPv6

Not supporting scope_id by wget means:
a) not suporting unrouteable IPv6 adresses
b) not supporting multicast

Bevore IPv6, wget also not suport unroutable IPv6 adress
I also think that wget do not wan't to support multicast since it is not 
used for FTP/HTTP.
This is the ground i think that it do not make sense to support scope_id.

If there are good examples where scope id is needed ( ftp or http ) i 
can think about implementing it.
Since ftp do not support symolic IP's on acitve or passive communication 
there should be only
link_local IPv6 examples running passive mode !!!
