What's the reason for limiting max core boost override to just 200Mhz?

My Ryzen 5 5600x seems to boost happily all the way to 4.85GHz on my B350 PC Mate in single threaded workloads with Curve Optimizer set to -30 and max core boost override set to 200Mhz. I'm curious why the limit is just 200MHz, why can't I push it as much as I want until my system becomes unstable? With a single core working, the power draw is so low I don't think it has anything to do with safety or any internal limitations, especially since at the same time I can push PPT, TDC and EDC limits much higher affecting the voltages and power draw in multithreaded workloads where it actually matters a lot. Seems like a completely arbitrary limitation.

I've heard that some motherboards allow for 500Mhz override. I've also read about some motherboards beings stripped off that functionality entirely with the newer bios updates which seems like a pretty bad move considering how useful and safe it is. Or maybe it's not safe? I honestly can't think of any reason for this hard limit other than the risk of damaging a cpu but I can't imagine how that could possibly happen with just one thread being stressed at a time.

May be it depends on CPU you have my 3900x is limited to 200Mhz where the 5900X is a limit of 500Mhz on the same board and same Bios

In this thread which I've just discovered a user reports being able to override the boost all the way up to 600Mhz on the Ryzen 5 5600x. So it seems to me it's an MSI thing and they could change it if they wished to.
That was done on a older bios over a year ago you can always roll back to a Older bios Any BIOS from AGESA 1.0.0.1 and up should work with a 5600X but I would advise against it.

I know, I just pointed it out to show it's not an intrinsic CPU limitation as your previous comment might have possibly suggested.

Bios limits are set by AMD not MSI.
