That's a perfectly valid decision; there's a good chance the trueness would be affected if you (or the shop mechanic) tried to balance tension.

Two minor things you can do to mitigate the possible ill effects of this decision. First, spin the wheel before every ride. Watch the rim (or distance between brakes if you've got rim brakes) and see if it's developed a lateral hop. If it has, a spoke has come unscrewed and needs to be tightened. Second, after roughly every dozen rides, do the plink test on the NDS spokes. Again, if a plink or a plunk has progressed to a thud, that spoke needs to be re-tightened.
