If it's possible to isolate that part of the code, and essentially freeze it for long periods. At least people would know it wasn't being tweaked under them all the time.

That is my half of a bad idea.

I have something coming out soon (just working on it). Your client (browser) has hashing algos built into it. So the browser can run a hash of all the front end assets it serves. Every commit merged into main will cause a hash of all the public files to be generated. We will allow you to compare the hashes of the front end files in your browser with the hashes from the public GH project. Interested to know what you think...

That sounds like a good idea. Any step toward transparent security is a good one.
