It's more fair to say that you cannot "combine" range syntaxes.

For example, `3.2.x` means "between `3.2.0` and `3.3.0` (exclusive)."  `> 3.2.0` means "between `3.2.0` and `∞` (exclusive)."  Given those definitions, `>= 3.2.x` would translate as "between (between `3.2.0` and `3.3.0` (exclusive)) and `∞` (exclusive)," which doesn't have a useful application.
