I proved to my own satisfaction that that was true, back in the 70s.
However, new replacement seals for at least the past 30 years or so appear
to be compatible with all brake fluids.

New fuel pump diaphragms are also compatible with ethanol, while originals
(or at least some older replacements) apparently weren't.
