Because we always talk about svn: being a special protected namespace and the
only property we ever mentioning changing is svn:log. We don't allow people to
add new svn: properties without our approval, likewise, up to know I assumed we
also protected the properties existence.
So let me change it on you where it says one wouldn't naturally assume svn:date
can be deleted. We have the -r {date} which implies its existence. Whenever I
read the docs for it did it mention it's behavior when the property is missing.
Does it say in the svn book?
And you're talking about at the API level, not at the user level.
