The benefit would be that - assuming the developer is well aware of this limitation - it would act as a disincentive to push code relying on the experimental feature to production.

It would however introduce a lot of hassle in testing the feature - being unable to work on a particular branch for all of every Tuesday. A better approach might be disabling it for an hour or two daily at 4am local time, or for 5 minutes per-hour, etc.
