Is mandatory !
Else you're lost.
For 0402 or 0201 the silkscreen is bigger than the component itself
(if you really want to read something) and when there is no room near
the component, all the component numbers could be grouped away in the
same map structure as components. Is the only way you could solve the
problem.
