Some simply consider split ring washers to be the work of the devil.

I found this looking for a more extensive set of videos of bolts
loosening, and the test rig used.

I didn't watch the rest; I notice they didn't say anything about the
torque applied on the test. Didn't appear to me it was more than just
"snugged down" rather than really torqued, but who's to know--they
cleverly didn't the applicator so can't even judge by looking the amount
of effort or size of ratchet, etc. While it may have been optical
delusion, looked to me like the bolt turned as well which wouldn't
indicate being very tight.

I don't have any scientific evidence but 50+ yr practical use on farm
indicates to me they serve a useful purpose.
