No,
You miss the point. Leaks are inevitable. Sooner or later you will have brake
fluid on your paint. DOT actually works at least as
well as LMA fluid so why not eliminate the problem that occurs when the master
cylinders leak.
I have also noticed that when the master cylinders get hot, LMA fluid expands
somewhat (and maybe DOT 5 does too). That causes small
amounts of fluid to escape from the weep hole in the top of the cap and onto
the paint. So even if there are no leaks you can get the
stuff onto your paint (Not to mention fools like me that can't pour straight)
So therefore the best of both worlds. Just because the Manufacturer didn't use
DOT 5 (not available back then) doesn't mean we can't!

P.S. Yes, rebuilding the system is recommended when introducing DOT 5. Rubber
hoses tend to weaken over time and will swell when
pressure is applied thus making the pedal feel spongy. And redundency is not a
bad thing, NASA uses it in all their systems. Better
safe than sorry!
