I wonder how hard would it be to build a extension for a browser that checks the doi of the paper youre looking at on scihub against the live version, to see if there’s a retraction/update to the paper, and list the date of the changes. I assume that information wouldn’t be behind a paywall.
The reason for it being via an extension is to reduce load on sci hub, and for the lookup requests to be decentralised and live for the relevant paper

It also rarely works for any paper/article older than 20 years.
Heck, my sister’s asked me to get papers she’s co-authored off of scihub for her, and those have been published within the last 10 years
