Not Canon, not Nikon, not Pentax,.... The SD Card Consortium solved it.
SD - Fat 16.
SD-HC - Fat 32
SD-XC - ExFat.
If you use an SD-XC card in ANY camera, the only reason to have short files, is the EU Taxation, where a 'Stills' camera and a 'Video' camera get taxed differently.
Canon, like a lot of video camera manufacturers, use region Specific firmware on many models, so those sold outside of the EU will be ignoring the EU limitation.
The easy way to do that, while making sure the user can't loose a whole card's worth of recording, is to split the files, so the camera writes video from the sensor to a buffer, and the buffer is big enough to soak up any stops and starts at the card.

I only use SD-XC, the Pentax's have had SD-XC controllers as far back as the K-01 / K-30 release, and they format to ExFat.
