Potential Approach

I've noticed similarities between Webfinger, which aimed to return JSON
from a DNS-like identifier with an "@" symbol, and your current situation.
Webfinger eventually established the acct: URI scheme. However, in 2012,
Mark Nottingham suggested an alternative lookup method, such as
".well-known/webfinger?user=bob@host".

You might consider registering an "atprotocol" under .well-known and use
the following format: ".well-known/atprotocol?user=<atproto_identifier>".
If the dereferencing is handled by the BGS rather than individual hosts,
perhaps a simple lookup would suffice, eliminating the need for a new URI
scheme.
