No, it is not necessary. It saves a few CPU cycles because the event
polling stops, the #step methods on the visible morphs are not called
anymore, and the display is not updated any longer.

Programmatically you can still do everything (headless or
non-headless). For example you can open morphs and move them around,
you just won't see a change on the screen. Code that have some
interaction with the GUI thread (like the debugger) might deadlock (or
hang) the system.
