Yep. And all that is before we even consider the technical limitations. Someone could request a dog companion, which might sound simple (other games had a dog!), but if the engine doesn't support, for example, skeletons or animations for quadrupeds, then it's super hard to implement such a thing. Modern engines support a lot of functions, but none cover all use cases (BW had to create the inventory and dialogue system from scratch for Frostbite). How do you explain that a simple sounding function could, with their set up, cost thousands and many months of work?
I'm just taking advantage of your remark about a dog (because, hey, dogs and cats are both pets, right?) to point out, to you specifically, that someone made a DA2 mod to give Anders a pet cat. It is the cutest thing ever omfg. This really should have been in the actual game since there is that one "putting out milk" scene. 
I have to ask, because BSN is making me incapable of reading people. In the Solas thread you asked someone, how they are going to rally people to force BW to write the story they want about the elves, and the answer was "I'm working on it." ...That was sarcasm, right? Or should I be bracing myself for a riot of very specific elf fans after DA4?
People on the BSN can get really weird about elves, and the weirdness expresses itself in so many strange and terrible ways.
I really can't understand this attitude from certain fans. It's a fictional race. I don't know... perhaps people are putting their real-world racial frustrations onto this fictional one, and because they can't do anything about real-world systemic racism they want to obliterate its fictional counterpart.
But I think that rather misses the point of the inclusion of these types of groups in the first place: that they are an allegory for these real-world issues and are likely not going away anytime soon. Also, I think the setting would be rather boring if they did, or if the dwarf caste system were suddenly eliminated. What is the driving conflict after that point? Just the abstract evil types of main villains, or something like the Blight? Doesn't that get old after a while?
Also, to expect that Solas will fix everything for the elves is incredibly naive. If anything, should his plan fail, or even just not succeed in the way he wants it to (the most likely scenario, since he can't predict jack squat), the resentment by 3/4 of the other races toward elves will be ENORMOUS and just lead to more hardships for them.
Nope, that was legitmate. And ridiculous. And when I responded they replied in Elvish.

Lol... how can that be anything other than gibberish? It's not like DA elvish is developed beyond certain phrases and words. It's not like Sindarin or Klingon, or something.
"A Riot of Very Specific Fans" might be a good subtitle for this place.
And a good name for an emo rock band.
