Not at all.

I do not interpret the LGPL version 3 in this way:
A "Combined Work" is a work produced by combining or linking an
Application with the Library.
So you must apply section 4, in particular, provide the "Minimal
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
So a binary-only is usually not appropriate.
