The /64 linknet allows us to use SLAAC instead*** of DHCPv6, which is something that sits better with the networking guys :)

If you want even less work, you could use neither on the WAN, just let them use link-local.

However, one advantage of serving a /64 directly on the PPP interface is it makes it easier to get a working IPv6 connection from a generic laptop in a troubleshooting scenario.

While it's technically possible to run a DHCPv6-PD client on your laptop, I wouldn't bet that you have that set up. On the other hand, I can get an IPv6 connection going with my hands tied behind my back if a /64 is served via ICMP RA.
