Huh?  This really shouldn't (at this late date) be a surprise to 
anyone.  RIRs allocate TLAs (or sub-TLAs) to "TLA Registries".  TLAs are 
the only prefixes that are supposed to be in the "default free zone" 
routing tables.  Ergo...

Ever since the RIRs existed?  See goal number 2 of section 1 of 
ftp://ftp.isi.edu/in-notes/rfc2050.txt or section 2.2.2 of 
http://www.arin.net/regserv/ipv6/IPv6.txt.  As to how it was decided, my 
guess would be "by default".
