There's a point to everything.  You need to use whatever suits what you 
want to do.

  ~:  This version and all revision bumps of it.
  =:  This version.
  >:  Higher than this version.
  <:  Lower than this version.
  >=: This and higher versions.
  <=: This and lower versions.

Note that "revision bumps" are not higher versions.  For example:

  ~some-category/foo-3.0.10

will match foo-3.0.10, foo-3.0.10-r1, foo-3.0.10-r2 and all "-rN" 
versions of it, but will *not* match foo-3.0.11 nor 3.0.9.  Just 3.0.10 
and all revisions of it.
