Might I suggest in the future purning down what you're responding to,
to just that blurb? At first read of your response I thought you were
arguing against the ABI var itself (which didn't make a helluva lot of
sense).
Meanwhile, yes, using preserve lib there still has some issues- the
reason I mentioned it possibly being held onto is that if we're
talking about something like openssl, having your system be horked for
the intervening period isn't a great thing thus it may be useful as an
option at the least.

That comment is in reference to if preserve-lib is still enabled for
the rebuild.
