This will prevent the server itself from being in main - but it can be
in contrib.

I think that it is a Work That Uses the Library. It is clearly
designed to work with the library by being linked with it. The
direction of the linking makes no difference IMO.

No, as the LGPL itself says:
| If such an object file uses only numerical parameters, data
| structure layouts and accessors, and small macros and small inline
| functions (ten lines or less in length), then the use of the object
| file is unrestricted, regardless of whether it is legally a
| derivative work. (Executables containing this object code plus
| portions of the Library will still fall under Section 6.)
