Very basic question regarding SITELINKS and object behaviour after their removal.

Hi all. Im looking for the "MS official response' on this simple scenario:

I create a sitelink between 2 Active Directory Sites and KCC internally auto creates object connections between dessignated domain controllers /Bridgeheadservers on each of those sites, and then DCs replicate. Everything is cool.

But what should happen with those object connections when I manually delete the sitelink because i dont want the sites to replicate no more?  Should KCC should remove them after x period of time or should I manually removed them? 
Im getting different answers and just looking for the official response, since my on lab testings the auto obj connections in both sites are NOT getting removed by KCC after Sitelink deletion and I dont know if that's by design or not. 

Thanks
