Whilelists: The OpenPGP-aware clients. There aren't so many of them,
so that's manageable.

There is a community providing keyservers (such as
pool.sks-keyservers.net). My impression is that this network is well
maintained and has worked reliably the last years.

Why should there not be a similar community approach for setting up a
(smaller) network of validating key server proxies.

DANE requires write access to DNS. I don't see that the average
OpenPGP user has facilities and knowledge to achieve setting up the
required DNS records. If you can't convince the big mail providers
(e.g. Google, GMX here in Germany, ...) to provide a reasonable
interface for their users, I'm afraid that this will not be a success,
