Seems just plain sloppy to me. Its not hard to measure these things.
For a stub in the middle of the slab, measuring over a 20 or 30 foot
distance, combined with the jossling of the cement pour, being off by
an inch or two seems pretty reasonable. For stubs near the edge
(probably the bathroom toilet and kitchen sink, for example), an inch
or less seems easy. But 3 feet? Most plumbers should be able to eyeball
to within 3 feet without even measuring. Anything more is sloppy, or
(on the occational pipe) just a simple and forgiveable mistake.

Will the rework cause any degradation of the foundation or plumbing?

depending upon how good your termite barrier is, it would provide additional
ingress openings for them. it would also make dealing with additional cracks
for tiling necessary, and if there was substantial digging under the slab to
get to the pipes in question, the patches in the slab could crack off and
sink, causing the floor covering above it to also sink or crack, depending
upon what that was.
