Certainly, if you are editing a text in Mongolian or Phags-pa that
uses variation selectors it is very useful to be able to switch to a
mode that makes the VS characters visible.
On the other hand, if you were reading a mathematical treatise that
used maths VS sequences that were not supported in the font you had
available, it may perhaps be preferable to have an invisible
functionless VS than intrusive square boxes all over the place.
So I would say that a font that does not support variation sequences
should follow Mark's suggestion and map all VS characters to an
invisible glyph, whereas a font (such as Code2000) that does support
variation sequences should give VS characters a visible glyph, which
can be available for use in "show hidden" mode, but which will be
stripped out by the rendering system in normal use.
But what a font should not do, in my opinion, is simply leave VS
characters to be rendered with the .notdef glyph.
