Ignore that. Or, rather, apply almost the opposite: never put any initial
text in an edit box or text areas, unless there are good reasons to expect
that the text would be a sensible default value.

It's simply a mistake in the guidelines. If you ask the W3G WAI group,
you'll get the answer that it's conditional under "until user agents..."
and that the checkpoint has become obsolete because current user agents
can handle initially empty fields well. But in reality it was a bad idea
from the beginning, causing trouble to the great majority (while
admittedly helping some people who used faulty user agents, long ago).

Unfortunately the WCAG guidelines are frozen. There's long process meant
to produce WCAG 2.0. Meanwhile, for years, WCAG 1.0 remain as once
written, and several authorities swear by them, usually without
understading much of them, or about their being out of date, in part.

That's one of the original problems. The initial content, if present, is
meant to provide a default value, not filling instructions. The very idea
of a default value is that it is expected to be suitable in many
occasions.

And because JavaScript might, and often should, be turned off.
And because the JavaScript code will also wipe out user input, if
the user later returns to the field to fix a typo, for example.

It's not a solution at all but creates a new problem: greyed-out text in a
field normally means _disabled_ input field.
