It shouldn't be. The tools should help.

JOSM has a plugin called Fuzzer which will trace from imagery (
http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Fuzzer), and a built-in tool
to square up edges. This should be ideal for getting building outlines in
with minimal effort, and I would recommend people use it.

Oh, ok then. Potlatch 2 has a similar squaring-up tool already (thanks
Matt), and will in time have Fuzzer-like capabilities. (There's a wonderful
ActionScript 3 library for that. There's a wonderful AS3 library for most
things, in fact.)

I don't know what the quality of StreetView is like in your area, but I
would weep if someone were to blindly trace from StreetView in Charlbury
without ever having visited it. The building outlines just aren't that
great. Let's not lose sight of OSM's strengths in an enthusiasm to slurp as
much free data as possible.

cheers
Richard
