Google used to explicitly ban this and the very similar practise of keyword stuffing - they even delisted some high profile company sites (BMW is one that I remember) over those practices. They stopped caring about that sort of thing quite some time ago, and right now as they are in danger of losing what little most they have as people move to AI solutions where they are not the leader that they have historically been in the more traditional search space, I doubt it'll be any sort of priority for them in the foreseeable future.
