Maybe 10 beers in you can convince me, but I don't see using the HTTP
contexts as hacks. To me, they have been around for 10+ years and software
uses them. That is a reality. You walk into any technical manager's office
and try to tell them you can't use contexts anymore and they will gladly
show you the door and hire some programmer willing to use them. There is
software in an ivory tower and there is real life. We are stupid not to
offer some way to access these contexts. Can we advocate not to .... sure,
fine, but I still think it is stupid to pretend they don't exist.

NOTE: While I make a strong effort to keep up with my email on a daily
basis, personal or other work matters can sometimes keep me away
from my email. If you contact me, but don't hear back for more than a week,
it is very likely that I am excessively backlogged or the message was
caught in the spam filters.  Please don't hesitate to resend a message if
you feel that it did not reach my attention.
