Hi Henri,

Actually the current draft says "consider" not "should add explicit support".

Something to take into consideration is the size of the farm. This
isn't acknowledged in the current draft text. For accessibility
conscious authors (small farmers) a table summary is indeed a cowpath.

Like I said to  Anne, one suggestion proposed in the Wiki [2] is to
change the name and definition to something like:

Consider Existing Practices. When a practice is already widespread
among authors, consider it. Widespread use (cowpaths) are one factor
to inform design decisions but not necessarily "pave" the way to them.
No set number of use cases proves a feature should be included or
excluded from the spec.

Another suggestion would be to eliminate the principle all together
because in fact no set number proves a feature should be included or
excluded from the spec.

The W3C requires that technologies must be accessible. By definition,
people with disabilities are a minority. Accessibility features
address failure modes that are infrequent, but usually critical when
they occur.

Thanks Henri I added that design principle to the table summary Wiki page.
