I'm disputing the conclusion that ULA-C and central registration is required to solve this problem, which feels like a complete non-sequitur. Just tell them to generate a shorter prefix meeting their needs, alongside a warning about what the future consequences might be.

Right. If I want to use fd00:bec0::/32 (BEC being my initials), I certainly can, and it will disturb nobody.

I'd be foolish to use fc00:bec0::/32, because who knows what it will be used for 10 years from now.
