Refering to a discussion on the user list, especially:
http://lists.gnu.org/archive/html/lilypond-user/2014-05/msg00425.html
I'd like to report some bugs/enhancements.

First:
the following gives a warning with midi:

\score {
{ c'1\> c' c'\! }
\midi { }
}

--> (De)crescendo with unspecified starting volume in MIDI.

Though

\score {
{ c'1 c'\> c' c'\! }
\midi { }
}

does not warn. From a _musical_ point of view I can see no difference
in the starting volume.

Second:
In order to avoid the midi-warning a workaround would be to specify
the starting volume explicitly and hide or omit the
DynamicText.stencil.

{ c'1-\hide\mf\> c' c'\! }
{ c'1-\omit\mf\> c' c'\! }

Though, the Hairpin will start at the right of the now
invisible/non-existent DynamicText [#4837].
I'd think "... the code for typesetting the hairpin should
explicitly check for an _omitted_ stencil (one being #f) and in that
case revert to the anchorless behavior", as David K pointed out.

Third:
According to \omit a shortcut for setting the stencil to point-stencil
may be quite handy.
