I don't really see the harm in providing people a option at least. The work is already done with cleric tags.
It was even further along than that. In the datamines paladins already had their unique deity-aligned lines already written out and ready to go for EA, but they scrapped it all for some reason when Paladin came out. Every deity had their own paladin-specific lines too-it looked great.
The weird dialogue in certain places of EA regarding Zariel's fallen paladins, or where your paladin mentions serving a goddess are the remains of all that hard work larian did that they weren't able to fully scrub out.
