Actually they they're not saving money.  Starting with the M series of 
cameras, that I'm aware of at least, (maybe earlier, I seem to remember 
something similar on the ESII, but I don't have one available to look at 
right now). Pentax incorporated a switch in the hot shoe, usually on the 
right side which interrupted power flow to the electrical contacts when 
a flash was not mounted.  The rational for this was that a user wouldn't 
shock themselves when using a flash attached to the PC connection,  
which was possible with a number of cameras IIRC.  That switch is 
missing on the *ist D, which has a PC connector, (probably the same 
function is done electronically), and though it doesn't serve the same 
function since the Ds doesn't have a PC connector, the the switch is 
present on the Ds.  The cutout is to keep from stressing the spring on 
that switch.
