Impacts of deleting an active update patch from a deployment package on clients

Hi All

I have stumbled upon a situation where in I would have to delete an active Windows Update from one of our historical windows update deployment packages.

Now, this deployment package is already distributed to all distribution points and clients (although it doesn't work). DMs have been created both globally as well as regionally.

My question is what is going to be its impact on clients in a production environment, if we delete the specific update from the deployment package and check "update all distribution point" apart from the fact that it must delete the update from all distribution points. (I am optimistic that I don't have to manually delete the package from the package source)! Do I need to consider something else??

Thanks in advance!
