.onion and .i2p (and to my knowledge, the other proposed P2P-Names
TLDs too) have to conform to DNS rules in order to be usable in legacy
applications that expect domain names. In some future where the
percentage of apps requiring this is much lower (by most apps natively
supporting Tor/I2P/etc), the restriction could be removed. But while
domain names are the de-facto standard, I don't see it changing.

+1. Besides the confusion, this would require native app support,
because URI schemes are generally handled separately to name
resolution - you couldn't just use a SOCKS/HTTP/DNS proxy to handle
legacy applications, like Tor/I2P/GNUnet do now.
