As a host developer I strongly oppose that. It will make life easier for
network operators but make life harder for host OS developers, host
operators, and host users.

And it is absolutely inappropriate to change this now in given that the /64
boundary has been the standard for the last 20 years. It will break
deployed code that relies on the current standard. (That includes concrete
code I can point to that I know runs on tens of millions of devices.)
That's not acceptable to do in a standard reclassification.
