Well - actually caching does work for COA and HMENU as well, but it is 
sometimes not very useful to apply it directly.

something = COA
something {
   cache.key = cachesomething
   10 = TEXT
   10.value = whatever
   wrap = blah|blah
   outerWrap = blah|blah
}

This would cache wrap, outerWrap AND the TEXT object, but still the only 
the TEXT object would be rendered with every request, even though it 
would be ignored by the output.

something = TEXT
something {
   cache.key = cachesomething
   cObject = COA
   cObject {
     10 = TEXT
     10.value = whatever
   }
   wrap = blah|blah
   outerWrap = blah|blah
}

This would cache wrap, outerWrap AND the TEXT object, but for the cost 
of an additional cObjGetSingle call due to the nested structure. So in 
some usecases it might not be too different to the first example.

In both cases there would be a fully rendered item available for the 
given cache key.
And this might be retrieved by a completely different method that would 
not make use of TypoScript at all. So even the first one would give you 
a cached result.
