Sling stud or Qd cup on foreend?

[Coopsdaddy]

My rifle has no provision for Qd cups but has the standard swivel studs.
I am going to buy a Srs arca/pic rail and noticed they have a Qd for the front.
There version unknown munitions sale is a little shorter and don’t have it.
Any reason to have just a Qd in front if you don’t have them anywhere else ?
I typically don’t even use a sling but thought I’d ask.
I would rather have the rail without it .

Some people tie off to be back but still want a QD "just in case". Its pretty easy to get the cups and mount your own QD spot of you want/need them.
