I think so, but unfortunately, this part lacks sufficient documentation.

Sorry finally circling back here. Reading the docs further, this seems to be just limited to supporting older lint versions. We only support the latest stable. With that said, is this still relevant? From what I gather in the docs linked, the actual change we should be making is to use getValue(context) instead of getValue(configuration).

Hmm, it does seem like maybe this lint doc is ambiguous. Going to update this to use this for backporting and incorporate the new findConfiguration behavior, and separately file an issue asking for clarity
