What? Paladins of Bahamut can't get non-cleric spells? Seriously?

[With a box]

Grant Spells
A deity automatically grants spells and domain powers to mortal divine spellcasters who pray to it. Most deities can grant spells from the cleric spell list, the ranger spell list, and from three or more domains. Deities with levels in the druid class can grant spells from the druid spell list, and deities with paladin levels can grant spells from the paladin spell list. A deity can withhold spells from any particular mortal as a free action; once a spell has been granted, it remains in the mortal’s mind until expended.

It means if the Paladin of Bahamut(dosen't have paladin level. it's a dragon...) can't get spell that isn't in both cleric's and paladin's because if it isn't Bahamut can't grant it to him....

should I post it in defunctional rules?

(p.s think about divine bard. or a druid...)
