No, it can still be fundamentally borked. It _is_ fundamentally
borked, it's simply the case that it's reasonably easy to compensate
for the fundamental problem by means of detailing the tubes
appropriately.

There _is_ a fundamental flaw, but they overcome it by putting in more
material than would otherwise be necessary. That it can be compensated
makes it no less fundamental.

I've always treated the magura rim brakes as fit-and-forget. They're a
closed system, and they use oil, not brake fluid, so there's nothing to
degrade. Mine are now 8 years old, and have never been opened.

Open brakes (ie any decent hydraulic brake) which use conventional brake
fluid may benefit from this sort of thing though.

Sorry, which part of a GT bike is made from thin-walled tube? FWIW,
Halfords Apollo hardtails used to have the same frame design (and may,
for all I know, have been rebadged GTs) but they didn't have any thin
walled tubes either.

Ah yes, the Bermuda Triangle...

I think you're mistaking GT for a maker of quality bikes. The things are
welded together from old scaffolding poles, anyway, and are so massively
overstrength (and overweight, of course) that issues of design elegance
simply don't enter the picture.

All bike tubes have thin walls.

A surreal moment for sure!

A sweeping generalisation that ignores the Zaskar, pretty much all
incarnations of which have been sub-4lbs (frame weight), despite having a
reputation for being bombproof.

I have heard opinion that the design helps divert vibrations from the
saddle, but IMO that also resembles the work of a marketing dept.
