Cost; I would imagine.

German cars tend to only have one foglight as logic dictates it is more easily distinguished from the brake lights. My BMW only has one. My old Volvo had one on each side and they really did look like brake lights. Had a dash mounted switch too, which I never engaged when being tailgated. Never.

As for reversing lights; I hate cars that only have one. It makes reversing in badly lit areas more complex than necessary. The Ford Focus is a case in point.
The Focus hatchback single reversing light, at the bottom of the bumper... agreed it's useless, but IIRC it wasn't actually as bad as it sounded mainly because at night, the tail-lights gave enough light to see behind. That, and you know there's less than half-a-foot between the bottom of the hatch glass and the edge of the bumper(on the Mk1 anyway). Reversing a Mk2 Focus saloon though, day or night, is a bit of a pig if you don't drive one often. No number of reversing lights will make that any better.

At work we had a mixture of Mk1 and 2 Estates all with factory fitted dog guards and generally a bootload of equipment blocking the rear window. Reversing was done with use of the side mirrors and guess work. Thus only having illumination on one side was a terrible idea.

Prepared for a flaming but how can a car be deemed roadworthy if it is carrying on illegal defect?
If the car was originally type approved with a reversing light and you then decide to remove it, it's not an illegal defect, it's an illegal modification. The MoT isn't intended to make sure that the cas was designed / built properly (that's the purpose of Construction and Use / Type Approval / IVA), its intended to make sure that the car is maintained safely.

Under 'Obligatory Lights', reversing lights aren't mentioned. Don't know if this has been superseded.

Please don't quote 'EU Rules' as they don't apply to use, only fitment, vis a vis DRLs.

When I built my Tiger kit car, I didn't bother with a reversing light - they weren't a legal requirement and it sailed through both SVA and MOT without bother. It has one foglight, mounted on the offside, although to comply with the law it can (could at the time, don't know if the regs have changed since I built it in 2001), be anywhere on the offside, including just a centimetre or two off the centre line of the car.

I find it odd that the mk6 pre-facelift fiesta only has one rear foglight and one reversing light, when the post-facelift cars have two reversing lights and two rear foglights confused

not even sure it has to be on the off side - to allow Pug 206 style single fog light in the centre of the rear bumper.

SVA regs definitely said offside, although I do remember Tiger building a couple of demos with them looking centrally placed on the rear tub. They weren't exactly central though, just a centimetre or two to the offside to comply. Perhaps Peugeot did the same?

You obviously have never bought a new car. When you buy one they ask you how much reversing you are likely to do after nightfall. You can then choose the extra light option
Is that what Chapman meant by just add lightness?
