I think they mean compatibility with old devices like 5-10 year old handheld devices that don’t get updates.
There was a period where very early digital cameras (think 1.2 megapixels) could only read up to 4 gigabyte memory cards, so camera stores had a stock of smaller cards for when people came in with ‘old faithful’ and couldn’t get the 8, 16 and 32 gig cards working with it.
I’m not sure companies want to risk a corrupted card killing all of. 2 hour recording where the practice of splitting into 4gig chunks for later reconstruction might mean only the latest 15-29 minutes of a recording is lost if corrupted.
