No doubt.  But that's a specific special case: when you're viewing a
diff of changes over which one has easy control (e.g., vc-diff of the
working tree).

I can see an argument for turning on highlighting of "introduced
trailing whitespace" (not in the context lines) by default for vc-diff
of the working tree, but more general ("pedantic") highlighting
shouldn't be on by default.
