Well I suppose that's not too bad a reason.

I suspect that they'd be interested in feedback over at v6ops list <v6ops at ietf.org>, https://www.ietf.org/mailman/listinfo/v6ops - especially if you can name and shame the manufacturer responsible. I know there's recently been some work on a standards (or could be BCP) document specifying what consumer routers should do/be capable of.
I think "router unable to accept other than a single /64 prefix" could be considered a hindrance to IPv6 takeup.
