Yep. The writers also retconned the
durability of changelings. Mirror Odo was killed instantly with one phaser blast. The Martok changeling required dozens of hits to still die a slow death. Also, Odo was knocked out by 1 punch from O'Brien, again knocked out by 1 rock in "Vortex," but perfectly able to withstand a barrage of boulders in "Heart of Stone." But people will still say, "It's...it's because Odo was inexperienced!"
When Odo was stating facts about his senses, he was making statements about his biology, not his experience. In later episodes, he was floating above Kira like the Northern Lights, but that didn't mean he suddenly had a sense of taste because he was more "experienced." If anyone can come up with an example of an experienced changeling having those senses, please share. Otherwise it's an unfounded assumption. [Btw, this is in response to other posts, not yours!]
