This is not very common unfortunately, I see people show up weekly on the IRC channels I hang out in, with non-working IPv6 because they hooked up their Openwrt router behind their ISP router and it didn't support PD (even if there actually was a /56 delegated to the ISP-provided RG).

Software vendors will have to work around this with IPv4 fallback just like you say, to ensure a good customer experience. They will invisibly to the user workaround the problem to hide this network deficiency. It'll cost everybody time and money without anyone really noticing.

sub-PD aka hierarchical PD only works in very specific topologies.
Which is why the IETF consensus went to another solution instead.
