Whilst the Grave domain might seem more appropriate for Kelemvor, Death is listed as Kelemvor's domain in the PHB on page 294.
Given that Death is a domain of Shar, Bhaal and Myrkul, all of whom are available to PCs, It seems likely that Death domain is planned.
True, but "Death" isn't really intended for use by PCs. Hence why it's not an available choice in the PHB and was included as a villainous option in the DMG.
I'm aware it's likely to be included though, simply because Bhaal, Myrkul and Shar are available as PC deity choices.
Unfortunately Grave clerics, along with Forge and Protection, are part of UA and so will not be included in the game.
I was aware that only PHB races would be included (though even that isn't the case anymore since we have Githyanki), so I was hoping we might get at least some of the domains outside the core books. That's a shame though, as I really like Kelemvor as a deity.
