The answer is no, it would not be sensible, so using the same logic, if you have access to metal sewing needles, why would you not obtain some and carry them with you? The same then applies to the thread, beeswax and maybe spare clothing buttons. It is just plain common sense to carry these items with you.
Here then are some items you may wish to consider carrying with you on the trail. Needles can do double duty used for removing wood splinters. Fine linen thread may be used in an emergency for stitching up wounds. Beeswax used to wax linen thread can also be used to seal tears in your oilcloth after repair.
