You’re coding safety critical systems and depending on severely non-deterministic tweaks to GC to get it to run right?! Where is this for? (Just so I can avoid it)
No need to know where this person is deploying this, if you want to avoid people doing stupid shit with safety critical systems you should just avoid going outside. Actually, avoid leaving the bed, as everything software in this day and age is basically just duct tape and cable ties put together in a rush to hit deadlines.
Have direct knowledge or worked with many critical systems in a few different areas (cannot get more specific for several legal reasons). Can confirm. I'm given to understand that legacy systems (think 30ish years ago) were much better engineered, but there's not enough Proper Engineers(tm)(r) to design (and build) all the critical systems that are necessary.
The biggest issues are that an engineer with the knowhow is expensive, a team of them is prohibitively expensive, a lot of companies outsource this work to different countries and make them sign onerous and dubiously-enforceable contracts, pay little, demand too much, and have incredibly unrealistic deadlines for the type of work that needs to happen.
You know how it is, if it never fails, you're throwing money out. That's the mentality of a lot of management types I've dealt with.

That's certainly one way to look at over five years of engineering effort, extensive systems testing, countless hours of automated regression test development, independent product quality verification, rigorous code reviews, risk assessment processes, mandatory four 9s call quality requirements, integration analysis of JVMs with deterministic GC, and so on.
