While Kelemvor has the death portfolio (and thus the death domain), I highly doubt he'll allow his clerics to raise undead under any circumstances. So having the death domain available would do very little for players, the grave domain from Xanathar's would be more appropriate.
As for Githyanki... like Gray Ghost already said the strong body type wouldn't be lore appropriate for them.
Clothing/armor appearance option will hopefully get patched in, we really need that (for weapons as well)
