As Greg said above, there's no NEC direct guidance on this type issue, but some Articles that can 'lean' toward it.
With comm jobs most issues seem to deal with future access to the 'space' the feeders may run through. That revolves around the wiring methods installed. Raceway thru space, end to end, no boxes, condulets, etc., I see no basis for any argument. The jobs installed in MC cable, or other allowed cabling are where the access comes into discussion. Some landlords include a clause within the lease for access, but that's a legal issue, not NEC directly related.
