Not at all. I thought of an unconditional line of text.
First one selects "Choose a mirror of the Debian archive" -> 
"enter information manually". The next page asks for a mirror hostname.
It could include a line of text with s.th. like "An apt-proxy from Sarge will
not work."

Of course this information would also be seen by people that do not need it..
But it would only bother people that have a "special" proxy. And I think they
may rather be happy about that hint than annoyed.
