Benefit of Publisher Common ID

Description

I have created a test page. I am able to see below json from pbjs.requestBids
"crumbs":{
"pubcid":"c4a4c843-2368-4b5e-b3b1-6ee4702b9ad6"
},

I will be very happy if someone explain to me what is the benefit of 'pubcid'?

It's just a way to create a pub-specific advertising ID for a user -- provided as a service to publishers so they don't have to do it themselves.

Please watch #3046 for the implementation of an ID module that should have broader impact.
