What requirement could an ISP impose on you for you to be forced to migrate the intranet to IPv6 (because of PI-hole)?

You could always place a small NAT-enabled router between your ISP's device and your home network.

The only problem I could see would be the lack of a (semi-)static public IPv4 address, which one could solve by renting a VPS.

My ISP is the French "Free". They provide a router that is difficult to swap with my own (it is possible, but it is way easier to switch it to a bypass mode). With this router comes a TV box that requires IPv6 to work.

When I replace DHCP/DNS with Pihole I need to account for that. While this is not a complex setup once you understand IPv6 you still need to learn it.

I work in IT so I tried to get myself to IPv6 several times but never had any reason to do so (despite self-hosting a lot and generally being a nerd). I had to do that this time and my uninformed opinion is that it could have been done so that it is much simpler for advanced users (but not yet networking experts)

So you had to learn IPv6 the same way you learned IPv4. The question is: was it harder ? It seems you wanted to know IPv6 without learning it because you thought it would be the same as IPv4. And yes the Free boxes are hard to work with if you don't want to mess with vlan and still have TV services.

I think this misses the point. An IPv4-only home network has a lot of benefits, simplifying whatever you to in it which relies on IP addresses which you'll have to handle manually in code and databases.

His scenario is really a PITA, where he's basically forced to migrate to IPv6 only because of IPTV. There might have been a solution by creating an IPv6-only VLAN just for the TV, while keeping the rest at legacy, but it's not really trivial.

IPTV with Deutsche Telekom is also a pain, because they feed it in a separate VLAN and the routers and switches need to handle IGMP messages properly (IGMP proxy, IGMP snooping).

I think the main difference is that when I learned IPv4, pure-v4 was sufficient. Today, you can't run a pure-v6 network; you have to deal with both. The closest you can get is NAT64, which 1. doesn't always work, and 2. is still annoying to manage. (Which sucks, because doing just v6 would be nice)
