Nick,

The draft does not require changes to address assignment policy.
SRv6 has been already deployed using IPv6 addresses already available to the operator.
As an example for Softbank (all this is based on their public information that they have reported): 
They have a /20 IPv6 prefix available from ARIN. They have deployed SRv6 using only one millionth! of their /20 prefix. 

Cheers,
Pablo.

    I'm a bit alarmed by the lack of engagement here between the authors of 
    this draft and the RIR community about addressing. This draft has the 
    capacity to require significant changes to address allocation / 
    assignment policy, but so far there's been no discussion about how this 
    might work within current or future RIR allocation / assignment 
    policies, or indeed upstream at IANA.  Could the authors provide some 
    information on how they intend to approach this issue?
    
    Nick
