Pete,

Thanks for the review. Agree that in general having a hole in otherwise 
continuous prefix is guaranteed to cause always some undesired side effects.

Regarding sending RAs I don't this it will be much of an issue, though.
Assuming SLAAC is used, then the requesting router would anyway be sending
a /64 in each RA on its downstream interfaces, thus chopping the delegated
prefix into a number of smaller prefixes. And if each downstream interface
have their own /64 prefix, then including a summary prefix shorter than /64
does not really work.
