Now I see what you mean, thanks.

The reason for this is that, because regular properties are versioned,
we subject to them to the same out-of-dateness check as we do file
data. You have to make your change "against" some specific base
revision of the property, and if that base turns out to be
out-of-date, then your change will be rejected. That's why directly
regular properties on URLs is not allowed: the out-of-dateness check
would not be possible, and the user would have no way of knowing what
she might be overwriting, even if she did a propget right before.

Indeed, that's what I thought you were proposing originally.
