Mutability is a property of objects, not types.
Some objects (numbers) are always immutable, others (markers, buffers, ...) are 
always mutable.  But objects of most "interesting" types (strings, lists, 
vectors, symbols) can be either mutable or immutable.
Some time ago, I filed https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43557 to 
document which objects are mutable, but unfortunately it's not yet fixed.
