An ADS-B In Question

So hands up who would want a box that can display ADS-B traffic on your current soaring flight computer but will/can not issue any warning at all as you collide with a threat?

I do, I do...!

Seems to me that simply having a picture of the traffic around you is
sufficient without all the whistles and bells yelling about an imminent
collision. There's another aircraft 5 miles away! Ho hum... Let's see
where he is on the next (or one after) update. Same relative clock
position (azimuth and elevation) only closer? Maybe a threat, I'll
monitor or deviate a little. Yes, in a busy airline cockpit, I can see
the need for collision warnings but, we're flying VFR and are supposed
to be looking outside. Knowing there's an aircraft at a particular
location and closing is all I need or want.

I'm not talking about gaggles or energy lines here. You have Flarm or
PCAS for those situations.

What I'd really like to know is why the FAA doesn't want to transmit all
aircraft positions in the blind. What is to be gained by denying me
information about local (to me) traffic just because I don't have a
particular box in the aircraft? Is it a bandwidth thing?
