But what is the objective reason for this lack of desire?

Well, I'm pretty sure that the current thread options are overkill and can
be simplified. For instance, on Linux the template currently claims

THREAD_CFLAGS="-D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS"

_POSIX_PTHREAD_SEMANTICS isn't used anywhere in the entire system, the
effect of _THREAD_SAFE is to define _REENTRANT, and the effect of
_REENTRANT is to declare getlogin_r(), which PostgreSQL sources don't use.
In other words, this can be removed.
