This may ultimately be merely a matter of taste, but my own preference 
mirrors yours.

I believe there is cognitive value in seeing the thing you're working 
on, and as you note a script is a block of text.  A good editor can make 
it easy to navigate that block of text, but altering how it's displayed 
is not without tradeoffs.

Folding hides complex code, but doesn't make it any simpler.  In fact, 
once could argue it encourages complexity by making it easy to ignore it.

Showing code as it is is like a mirror to your mind:  you can't ignore 
the blemishes.

If a handler is so long that folding would seem useful, sometimes that 
can be an indication that it might be useful to consider breaking it 
into subroutines.
