Biggest mistake for IPv6: It's not backwards compatible, developers admit

I've seen this done with v4, it doesn't work. The deaggregators
often won't advertise an aggregate. Customers complain and you
end up making exceptions or the customers go away. Loads of hassle
either way

The ones that cause the problem aren't sane, they make it your problem

That is the problem, while most accept the insane routes you have to
accept them too. The only way to have sanity is for there either to be
no way for it to happen or everyone agrees to not let it happen. With
the latter there's always someone willing to accept insanity to make more
money at everyone elses expense.

I think, more so with v6 PI now possible, the loss of deagg TE may
be a price we have to pay.

If you make a game people will play it
