The downside should be obvious: you waste extra CPU and memory when you 
only need some of these values, and not all of them.

Which is the case most of the time, IME. That is, for one command I only 
need 'doc-buffer', for another - 'location', 'suffix' and 'kind' might 
be displayed together (though in your example they are duplicating one 
another) on one idle timer, 'docsig' is used in another idle timer.
