No, really; that's the way it _should_ be--for two reasons:
(1) It's a defined standard, specified in hier(7).
(2) Code libraries ("data" for ld, by your description) are indeed special.
Making sure they are not corrupted or vandalized is important to the
security and reliability of the system (especially shared libraries),
so they should be segregated in their own special corner of the
filesystem so they can be watched carefully.
Of course, it's true that lib used to be a catch-all directory, and it's
unfortunate that after the split we're left with so many who remember that
legacy and continue to live by it, but the "new" way really is better.
And we can't afford to be "flexible" (or "broad minded") on this--if we're
to have a standard organization for the filesystem, we need to follow
it scrupulously. Otherwise it's useless.
