I had seen that it was possible to charge the EOS R from a USB-C powerbank (see Amanda Woolsey on YouTube), but hadn't seen anywhere that showed that you could charge the EOS R from a MacBook Pro's USB-C port. Apologies if this is already known, but I didn't see it in any Google searches.

I connected my camera to download photos, then turned it off while still connected and the charging symbol appeared. See
I'm pretty happy with this, because it allows me to travel even lighter - no battery charger or other adapter. Shoot during the day, charge overnight, which is a common usage scenario for me.

EDIT: P13 of this says that you shouldn't https://www.canonrumors.com/wp-content/uploads/2018/09/EOS-R-PDF-Specifications.pdf , but many of the resources I've seen said you couldn't charge in another way. Having it plugged in via USB-C to a computer, though, is a pretty thing to do, so I wonder what will happen? I'll keep an eye out for problems and report back if I find any.

It will charge from any charger that implements the Power Delivery (USB-PD) standard. The warning in the manual is likely because there are a lot of 'fast' and 'quick' chargers that do not implement PD, but do allow for a high current draw. And those are the ones featured in the "Burst into fire while charging" headlines.

It charges from a few sources, that's what has been said. Most of the USB chargers won't work. DPR tested a few sources and indicated that some do work. Most will just not work when you use a usb-a to usb-c adapter cable.

Even if I found a cheap 3rd party charger to work (my fairly expensive ones do not), charging in camera is a risk, even more so with a 3rd party battery. Batteries are prone to overheating and swelling, I haven't seen that with Canon batteries, but I use them with a Canon charger. Batteries could ruin your camera if they fail in that way. Canon won't warranty the camera if it fails due to using the wrong charger.

I once bought a used Sony with in camera charging that had failed that way, the camera grip area was bulging due to apparent overheating and swelling of the 3rd party battery. I spent 2 hours drilling out the dead battery very carefully until only the outer shell remained, and then collapsed it to remove it. The camera grip did mostly spring back, and actually worked with a new battery installed. It came with another 3rd party of the same brand that I junked without trying.

I usually use Aukey or Anker 3rd party chargers, the better ones usually cost $50 and up, but I found a low end one here:

You can also get usb battery packs that have the USB-c power delivery standard.
