Yes it is silly, only if you think all data that HTML serves requires TCP
like transport semantics. Moreover, HTML specification doesn't specify what
semantics to use for transport, right ?
However, content may impose those semantics.

Say, you are streaming video/audio over HTML like Flash, quicktime.  This
necessarily require TCP like semantics because delay due to packet
retransmission or HOL blocking is bad (when serving real time data).
However, if you are using a transport protocol like
UDP  you might experience small disturbance, which is better than stalled
video/audio. This
is one reason that I can think on top of my head.

   It could be sued for a lot of things other than Apache itself.

I completely agree they might be using for totally different purpose. I just
started diving into the
code and trying to make sense of it.
