I think the notion that because one does not document something, it's
not an official part of the ABI is at best highly dubious. Especially
when so many "official" parts of the ABI are also not documented.
The only way that documentation might be able to help in such
situations is where pieces are clearly and loudly documented right
from the beginning, in the official documentation, as "not supported,
may disappear at any moment in the future, use at your own risk", but
even then people are likely to ignore the documentation or be unaware
of it.
And in any case, these environment vars have long been documented in
various "unofficial" places including (since 2012)
http://man7.org/linux/man-pages/man3/mallopt.3.html
Cheers,
Michael
