In "Help keep accessibility and semantics in HTML" [1], Roger
Johansson comments that:

The proposed HTML 5 design principle "Pave The Cowpaths" [4] does
indeed seem to condone many practices that past specs  may have
frowned upon. "Pave the Cowpaths" is an underlying principle being
debated in many* of the recent semantics and accessibility threads on
public-html@w3.org.

Thus I don't think it's appropriate to include this in the official
design principles.

"The Calf Path" [5] by Sam Walter Foss (1895) was a "popular humorous
poem during the early days  of the good roads movement. In the poem,
Foss describes how a crooked path originally carved by a calf walking
home developed into a major road traveled by hundreds of thousands of
people." [6]  Foss talks of of blindly following a crooked cow path
course.

More recently, in 'Don't Pave the Cowpaths' [7], Mike Arace discusses
why codifying bad practices may not be a good idea.
