Why was section 1 added to LGPLv3? My understanding of section 3&4 is, one can convey the combined work under any license and with no requirements from GPLv3 (besides those explicitly stated as requirements in LGPLv3 3&4). Given that, why is section 1 necessary. Wouldn't that sections 3&4 by themselves already imply anyhow what section 1 explicitly states?

I assume that I'm missing something and section 1 isn't redundant. Assuming that, does this have implications for other sections in GPLv3? E.g. does conveying a covered work under sections 3&4 fall under the patent clause of section 10 of GPLv3? Why does section 1 not also state an exception for section 10?

Put another way. Is the Eigen FAQ correct by stating:

LGPL requires [for header only libraries] pretty much the same as the 2-clause BSD license.

It it true that for conveying object files including material from LGPLv3 headers no GPLv3 patent clauses apply?
