No. Just those commands that are not intrinsically attached to a note

that you'd occasionally attach to <> or s1*0 for lack of something more
suitable.
In the case of dynamics, you really have 2 cases to cover: first, dynamics that
coincide exactly with a particular note (the current default case in Lilypond)
and second, dynamics (and this includes hairpins etc.) that are offset relative
to a given note. So, whatever is decided regarding whether the dynamic command
comes before or after the note, there needs to be some tidy shorthand for
illustrating the offset; and it needs to be possible to attach more than one
dynamic indicator to a given note.
Example: consider a half-note where you have a \p dynamic falling on the start
of the note; a \< hairpin that lasts a quarter-note; an \f dynamic that falls on
the second quarter of the half-note; and a \> hairpin that falls across the
remainder of the half-note (i.e. it also lasts a quarter-note).
The most simple way to do this is to add a parallel voice containing,
s4\p\< s4\f\> % ... etc.
but in practice you'd probably have to put in place some tricks involving hidden
quarter-notes in order to get the spacing right.
So in practice you might prefer something like,
c'2\p\<4 \f\>4
.... i.e. where some dynamic elements can be given a duration.
If you wanted to have e.g. a half-note where a crescendo starts halfway through,
you might have something like,
c'2\p4 \<
Or you might have a note where the dynamic changes suddenly in the middle:
c'2\p4 \f
(These particular syntax ideas may be unworkable in practice, but you get the
idea -- dynamic events [and possibly some articulations too] can have length in
their own right, and we need a way to indicate this; and horizontal spacing of
dynamic elements will need to take these factors into account.)
