Measuring multilingual page translation drift?

Is anyone aware of an implementation (in a multilingual Hugo site) used to measure the drift of non-default-language page translations relative to the corresponding default-language page?

An example of this would be to include, in the non-default-language page front matter, a permalink or permalink equivalent (such as a repo commit hash), to the corresponding default-language page. (Then, of course, extra code / tooling would be needed to measure the drift if any.) Is anyone aware of such an implementation? Thanks!
