Discrepancy between inner text objects for empty delimited blocks

Executing the inner object of an empty HTML element will select the outer object:

<p> text <i>|</i> text </p>
dit
<p> text text </p>

Doing the same with any other kind of delimited block, say, a parenthesized one, is just a no-op:

(defun (|) arg)
dib
(defun (|) arg)

Theoretically speaking, this looks like inconsistency.
Is there some subtle practical value in it?

(The behavior is documented in :help tag-blocks, but there's no explanation as to why it only applies to tag delimiters.)
