How old is your Mog?
How long before the original systems deteriorate?
Rubber tubing ages so will need changing. Seals age too. Electrics...some areas are really exposed ( look under your front wings!)
When I had my 1993 4/4 I replaced all flexible fuel lines, fitted an extra filter, flushed the tank etc as a precaution as she was 20 years old.
Same with the brake system, new flexible pipes, no visible leaks from seals so no cylinder changes done.
On my Plus 8 I have had to sort out front light issues due to corroded bullet connectors. A bad design as they are hammered by spray from the tyres.
To me, changing brake fluid is a no-brainer.
I do worry a bit about the removal of MOT for older cars as it is then down to the owner’s attitude to checks/preventive maintenance on ageing or old design cars.
