I can definitely see your way of interpreting this! <3
"As far as the game's rules are concerned, it doesn't
matter if your world has hundreds of deities or a church
devoted to a single god. In rules terms, clerics choose
domains, not deities, so your world can associate
domains with deities in any way you choose. "
-Dungeon Master's Guide Pg. 10
I will respectfully disagree with your interpretation.

However, like you say, there are few domain's to concern ourselves over for EA!
