I don't really see why Intel's opinion on this matters much. The requirements for this are price and power efficiency, not any of the features that Intel likes to class as "server CPUs" (eg the remote management features). The only downside is the lack of ECC memory, but some Celerons support that, eg[1]. It's true this one doesn't but that seems the only downside.
