Many do, and Vivi doesn't do that yet.  That comes under the topic
of "expressive music performance", which is a few steps down the
road.  There's a few examples of variable skill (including
applying a normal distribution to the timing) at the bottom of
this page:

Most research on expressive music performance uses piano or
perhaps guitars -- for those instruments, the sound of a note is
pretty much determined by the initial pitch, time, and velocity.
(leaving aside quibbles like guitar glissando, piano pedaling,
etc)
