Do I only need that tweak if I want to use cardano-cli against a p2p enabled cardano-node?
As it is currently, I’m planning to leave BP and at least 1 relay with p2p turned off, and have just one relay with p2p to “get best of both worlds”.
If you run in normal mode, then cardano-cli works fine with and without this change.
I can confirm that my block producer and 2 different relays have been running in P2P for several days, and I have produced blocks. I have nodes compiled for amd64 and arm64. I haven’t noticed any problems.
