The new ruling is a good thing, self assessment, and self policing by responsible owners will not cause a problem. High end stuff, the likes of Jaguar, Aston Martin, Ferrari etc, are generally wrapped in cotton wool, and want for absolutely nothing. Low end stuff the likes of Minors, Beetles, Ford 100E's and earlier examples are dead simple to work on, and parts are readily available for next to nothing, so its not a money thing... Nearly ALL pre 60's cars run on drum brakes, so would need constant maintenance anyway, regardless of an MOT inspection.
Nearly all pre 60's cars run a separate chassis... so do not suffer the same rust problems a Monocoque would suffer! If its made it over the last 50 years, then its likely to last a whole lot longer
Lighting on ALL pre 60's cars is appalling, so N/A
All Pre 60's cars will run 2 or 3 fixed point seat belts, (If any at all!) so faulty inertias will not be a problem
Pre 60's cars have THE most basic suspension, that is pretty much agricultural with only the Trunnions on front suspension giving any cause for concern... regularly greased, they are fine for many years/miles, and there are clear warning signs long before they fail.
Fuel pipes, generally copper or brass, right up to the carburetor, with only a short piece of rubber hose to keep an eye on.
These cars are people pride and joy, and want them to last another 50 60 70+years
Cant see a problem myself
