In the exact same way as the idea with previous versions has been to
max out a single cpu to 100%.
What do you expect? POV-Ray is a rendering software. By default it uses
all the available resources.

100% CPU usage doesn't mean that nothing else *can* use the CPU. It means
nothing else is *using* the CPU *currently*.
I think this is a rather curious misconception some people seem to have.
Just start another CPU-heavy program and you'll see that the OS nicely
shares the available CPU resources among them. POV-Ray doesn't have to
share CPU with anybody. The OS will force it to share.
Also in most OSes you can set priorities to processes. If you give a low
priority to POV-Ray, it will take 100% when it can, but if some other process
requests the CPU, it will get more of it.

If your computer is built properly it should stand 100% CPU usage for
days continuously without problems.

Not because it would somehow deliberately avoid doing so. It's just that
the OS and other processes do something else at the same time, so POV-Ray
doesn't get everything.

I honestly cannot understand how that is "silly". That's precisely the
whole idea in multithreaded rendering: To use *all* the available resources
to render faster. Most modern renderers do that, and if any renderer doesn't,
it's considered old.
And you *can* make POV-Ray use less threads if you want. There's an option
for that.
