In my experience mainframes at financial institutions are hidden behind IBM middleboxes that are specifically designed to obviate the infrastructure risks. It's a classic example of a company selling you both the problem and solution.
That's just an example of incremental improvement. Mainframes and midranges adapt with the times without losing what works. Modern midranges, for example, can run C, Python, bash, and web servers.
