I don&#x27;t want to come up with potential issues just for the sake of preventing this. But it&#x27;s my job as an engineer to think about all potential issues and to avoid them as long as possible. And I&#x27;m not directly involved in this topic here or in the web in the large, but I just read this and have wondered if this is fully thought through or not and asked therefore.<p>Of course domain changes are unlikely. But nevertheless they are possible in our system and we have to cope with it. I just googled subresource integrity and it doesn&#x27;t seem like an appropriate solution for this scenario. This would mean a new domain owner would need to generate those for ALL his links - just to be sure that the previous site didn&#x27;t mess anything up. This means at first extra work and second you wouldn&#x27;t even know for how long you need this (until all previous users have visited the new site).<p>There would be even possibilites for major annoyancies, if a previous site owner put that feature on things like index.html before owner change - just to avoid that visitors see the new page as long as possible.
