Running mix xref trace triggers a consolidation warning

[DavidVII]

Elixir and Erlang/OTP versions

Elixir 1.13.4 (compiled with Erlang/OTP 24)

Operating System

MacOS 12.4

Current behavior

I'm noticing this issue after upgrading to Elixir 1.12.3 -> 1.13.4 and Phoenix 1.6.6 -> 1.6.10 when I run the following:

$ mix xref trace lib/ros/accounts/user.ex
> warning: the Inspect protocol has already been consolidated, an implementation for Ros.Accounts.User has no effect. If you want to implement protocols after compilation or during tests, check the "Consolidation" section in the Protocol module documentation
  lib/ros/accounts/user.ex:11: Ros.Accounts.User (module)

The referenced code looks like this:

10  @derive {Inspect, except: [:password]}
11  schema "users" do

I've read the Consolidation section and it's unclear to me if this is an actual issue or if I can safely ignore it.

Expected behavior

It was mentioned here that this is safe, but that we should either document this warning or update mix trace to avoid this warning.
