This is similar to what we did in commit 00a5dc921 when upgrading to
Rails 5.2. Quoting from that commit:
> Note this change will cause all fragment caching to expire. We
> consider it acceptable considering the page where caching is most
> important (stats) is barely affected by this change, since this change
> only affects the view, and the time-consuming operations are cached in
> the model.
>
> Comments are actually affected, though, and pages with thousands of
> comments might take a few extra seconds to load the first time they're
> accessed after this change. We don't think this is going to be an
> issue on existing CONSUL installations.
