Thanks for considering.

hi!
I've commented in the pull request. As the workaround, you can just exclude these messages by text.

[gtalarico]

exclude by text worked; leaving a reference here for others:

The following worked for me (s/composites/composite/):

This should now be configurable (see: https://github.com/golangci/golangci-lint/pull/697).
