Hi, you see Zeitwerk in the stack trace because it decorates Kernel#require, but if you look at lib/zeitwerk/kernel.rb#38 you'll see that comes from the original Kernel#require the lib is wrapping.

That is, the warning is not really issued by Zeitwerk.

@fxn got it, thanks for the quick response. I will close this issue.

For others stumbling upon this, you can add something like puts caller.first if path == 'observer' to the afformentioned file to find out where the require originated from.
