No it's not, in general. It has to be considered on a case-by-case basis,
depending on:

 - *how* bad at X language B actually is;
 - how difficult it is to hack language B to be good at X;
 - whether anyone cares enough to do the required work;
 - whether changing language B to do X would introduce too much
   complexity or other disadvantages that would affect its use in
   other areas.

As for the 'shootout', most of the criticisms of it in this thread have
been valid; it's not a very good basis for comparison of language
