I think it was because I thought libraries and applications that
are linked without symbol dependencies would always get the
latest version of the symbol, not the earliest version of
the symbol.  But if I recall correctly from prior email from
you, you should get the earliest version of the symbol in
lieu of no recorded symbol dependency?

No argument here, go for it.
