You would need to say what that IRC user needed to find out. Depending on
that, letting the user know that there is no point reading on early and
not waste his or her time may be a good thing. That was what the paragraph
was designed for. IOW, it is not to "scare" away, but to allow the users
to decide if they are intended audiences.

The reworded version does avoid sounding scary, but loses the "this
document is for people who want to write new or understand existing
Porcelain scripts", which is a documentation regression.
