UpdateTip logs appear in debug.log unsolicitedly I'm running Bitcoin core daemon v0.17 on Ubuntu 18.04.
bitcoind -daemon -debug=addrman

Why do I receive UpdateTip logging in ~/.bitcoin/debug.log?

It is just simply annoying since I want to check logs of Addrman only.
Turn out the validation.cpp is performing many checks and they use LogPrintf() instead of logging tag. 

So by default the debug.log always include them.
