No issues thus far and no worries. I'm going to chuck this all off as some "odd imports" from my old host.
It happens sometimes, especially with dns records. It's good to go in and clean it up every now and then...esecially after a move.
There were times I would find some records still had old mx IP's I stopped using years ago. Anytime a site was moved, it would just add the new information with the old. Usually if the host is doing the move, they will look this over and clean it up.
Just keep in mind that some of these records may be used by the system for internal operations. I do agree that cPanel has gotten a little agressive about how they handle default DNS settings, but be careful about aggressively removing them.
Once you ascertain 100% that nothing is broken, you might want to consider modifying the default DNS template so that those entries do not come in with any new accounts/DNS profiles you set up going forward.
I would recommend that you leave anything dealing with internal operations (webdisk and localhost) alone, though.
