If people really think this is a problem, they'd contribute a non-abusive solution. Writing cron jobs to pull periodically in order to artificially reset the timer is abusive.

Non-abusive solutions include:

- extending docker to introduce reproducible image builds

- extending docker push and pull to allow discovery from different sources that use different protocols like IPFS, TahoeLAFS, or filesharing hosts

I'm sure you can come up with more solutions that don't abuse the goodwill of people.
