If you don't use it at all, they do take the prefixes away. I lost a prefix when I did a house move and a server move and took a couple years to get around to setting up the tunnel... They didn't undelegate the DNS until I poked them to either please let me have the prefix back or fix DNS.
I have native ipv6 at home and on my hosting, so that's nice. Unfortunately the he.net tunnels are used for a lot of abuse now and you treated like a bot if you use them to go to popular websites. :(
Many people, including myself, tend to look at .arpa and think "oh yes, thats PTR queries" but forget the DNS doesn't have a global rule that ONLY the PTR query can be sent to the domain.
It's just a domain. You can put anything into your zone. A, AAAA, PTR, TXT, you can even put HESIOD records if you want to party like its Kerberos nineteen ninety IV.
