I don't understand the question. I'll try to answer what might be the
question; if this doesn't answer you, please re-phrase.

Bazaar can use HTTP as a transport for file-level operations; that's
what a ‘http://’; URL specifies. The server doesn't need to be anything
except a static HTTP server.

Bazaar can alternatively use HTTP as a transport for Bazaar “smart
server” commands, requiring a Bazaar server to be answering at the
other end. That's what a ‘bzr+http://’; URL specifies.

My point is that a URL of the form ‘http://’; would be common, for
repositories that are available publicly only via file-level HTTP, but
uscan would not know from the URL which VCS tool to use.

In other words, encoding the information about which VCS tool to use
is incompatible with my request to preserve the URL for use as-is
outside ‘uscan’.

That's exactly what I began talking about: I want uscan to gain the
capability to retrieve a specific, identified working tree state from
the VCS repository.
