I've seen the ticket.

It is as easy as adding a `depends: tor` line to the debian/control
file. In modern Debian or recent Ubuntus, it is fine.

You're over thinking it. Connecting to the Tor Project website often
fails - far more than the Tor network being blocked.

Such users have a valid concern but I hardly think that this package is
for such users - as it stands right now, that problem is made worse by
both connecting to Tor's website *and* the public network.

It is easy - never allow a valid signature with a lesser version number.
