Curious what people think about this

Problem statement:
With the rise of web based services like Mutiny Wallet.
A commonly voiced concern is what guarantees private key security, what happens if they change their code the next time you log in?

Proposed Solution: 
A link forwarding service that notifies users if the code to a site has been altered. 

User Flow:
-Users bookmark the forwarding link (instead of the regular direct link)
-Forwarding link takes you to the site as usual

-If the code has changed, then it redirects to a “new build notice”  
-Users can see notes from the site owner and comments from nostr users (is it safe etc.)


This may be a big step for web based services which rely on private key management
