This is an odd response in my perspective.

'I don't like it because it's not secure and I was able to get access to prod via this method.'

'That method has been fixed.'

'Well...I still don't like it.'

Bugs are being found and fixed all the time. As for a the different plugins need different versions. Yes. This also occurs in general coding to where every package or library that you want to use in your code is also going to be versioned. If that package or library gets updated, your code might break.

This goes back to having some things in place. Backups and a maintenance and testing schedule. If you don't test things before pushing them out to prod maybe fix that first.
