It really isn't. I usually hold my threads down when I begin to chain piece. You could also begin on a junk piece of fabric and either way prevents "bird's nests" from forming and you having to deal with them.
But, if you're organized and can plan ahead you could make entire quilts with leaders and enders. I have a couple of Bonnie Hunter's books and this is what she teaches. I took a workshop from her and began one of her quilts. If you're focused on this (I am not), you could accomplish quite a bit with just leaders and enders.
You can also check your thread tension and stitch quality if it has been an issue. This way it prevents you from having to rip out unnecessarily.
