Obviously this isn't legal advice, but it's what defense lawyer friends have suggested if it ever comes up.
I think that popular video about "never talk to cops" mentions something like it too?
I assume if they don't wait, it helps your court case. They could always go with the "probable cause" argument, but again this can help your case if you can prove they didn't have actual cause.
Pro-tip: if they're at your door with a warrant, they have probable cause.

Think about it: say someone has a bunch of drugs, you wouldn't want to give them time to start flushing it down the toilet while they call up and verify the warrant is valid. You kick the door in, arrest them, and secure the scene for forensics and evidence collection.
