As nice as DANE is, it just shifts the burden of trust to your DNS provider. Like if you hop on Wi-Fi at a coffee shop, said network can simply MITM connections and supply their own certs via re-writing the DNS.
It can't, because DANE requires the use of DNSSEC. Unfortunately, there are still so many domains that do not have a proper DNSSEC configuration… so it's unlikely to work out well in practice, anyway.
edit: not to mention the DNS is centralized too. It's federated, at least (in the original sense of the word, not the way it is used on the fediverse), but ICANN is still the only central authority at the end.
