Maybe I’m misunderstanding what you were going for here, but I’m pretty sure when someone buys the game, they are paying for what the product is, not a perpetual train of free additions, although I dare say we’ve done an extensive share of those, many of which were taken from community requests over the years.
What matters to us is how we are investing our resources. Top priority, being a business, is obviously to stay in business. Oftentimes, that need overlaps with the desires of the community as we introduce desirable features for players which in turn attracts new players.
As time and resources are not infinite, and there are diminishing returns to be considered, we have to weigh various features against each other and decide what’s going to have the biggest impact, what will appeal to the most players.
As we’ve said a number of times in the past, things like Menu Backgrounds or Load Screen selection did not seem as critical to the majority of players as say…loot filtering, search functions, monster totems, overhauled old skill fx, overhauled melee animation tech, updated old monster models, deferred rendering, dynamic skill lighting, auto-looting…
Remarkably, item/skill refining doesn’t take artists. And having to make that clarification is why we also say things like this…
Although you took that way too seriously. 
Not to mention how much of our work over the years WAS focused on aesthetic, so your statement is simply disingenuous, or perhaps not aware of all that we did in game updates, in which case I’d recommend going down the memory lane of dev updates.
No, we do not, but we do need our TWO artists to contribute to the array of projects we have going on at the company right now. Things that are more important than upscaling class art to meet our high standards required to be suitable for load screen art.
I’m not sure where our “want” comes into play with feature requests such as this. I don’t have any personal investment in whether this feature exists or not other than I don’t care about it in other games at all. My “wants” are entirely irrelevant and have been in the past when we’ve added features requested by the community.
It continues to be as simple as we do not consider the time and resources required for this feature to exist to provide enough value to the GD playerbase to outweigh other priorities.
Damn, I should have read this part first! 
Not to mention, as mentioned in comments above, the game is moddable to your heart’s content. You can change the main menu to whatever you like.
