It depends on how one is handling things.
If a DM simply says, "we're only using WotC D&D books and content, no questions asked" that takes virtually no effort at all.
If a DM says , "we're only using WotC D&D books and content," but the DM will allow players to come to him with non-WotC material so he can then make a judgement call about allowing it or not (instead of just automatically dismissing it), that takes a modicum of effort.
If the DM instead allows all the WotC D&D books and content and then takes it upon himself to scour thrid-party material so he can compile a list of things allowed and not allowed, then he's doing more work than he really needs to.
Alternately, you could have a situation where the additional material is also created by WotC. In that situation, the various scenarios would be more like this:
If a DM simply says, "we're only using the options from the PHB (or PHB and DMG), no questions asked" that takes virtually no effort at all.
If a DM says , "we're only using the options from the PHB (or PHB and DMG)," but the DM will allow players to come to him with other material so he can then make a judgement call about allowing it or not (instead of just automatically dismissing it), that takes a modicum of effort.
If the DM instead allows all the options from the PHB (or PHB and DMG) and then takes it upon himself to scour other WotC material so he can compile a list of things allowed and not allowed, then he's doing more work than he really needs to.
Or you could simply say everything from books AB and C.
Done.
