Because then all apps are linked to it, also the ones that don't need

If the widestring manager could be made by ourselves, is it possible for
thread manager as well?
Principiall yes, but the problem here would be external code that the
program links to. E.g. Wine did something like this some time ago
(before they switched to pthreads) and needed to simulate some
structures so that libc switches to multithreaded mode... So if we have
Pascal only code (like the compiler) this would work without big
problems (if someone implements it of course ;) ), but if you have 3rd
party code not written in FPC then problems might arise...
On the other hand, if somebody's linking in "alien" code then he should
make himself aware of aware of the prerequisites, particularly since the
threads are more likely to be in the main program (i.e. stuff that he's
written) than in the library he's pulling in.
Going back to something less labour intensive, would it be possible to
have s directive which has the effect that if a procedure isn't
eliminated by smartlinking then the linker should warn if a specific
library hasn't been linked?
