I don't mean to put any one on the defensive here. I apologise if I come off bluntly; this is meant to be a respectful discussion and that takes effort from both parties.
I think the future of Blockland has always been relevant. We haven't even been ignoring it; we just responded in different ways. We're at a unique point in this game's history and I think, especially now, we need to think about where we want to head as a community. Of course, this assumes a perfect community capable of mass coordination, which we aren't, but I think if a kind of movement strong enough exists, we can all benefit from it. I would also point out that, even if we only just now thought about it, it's always been important, and always will be important.
I don't think it's really fair to say that brick-based structures look objectively ugly. That itself is completely subjective, and doesn't really hold weight in this context regardless. As has been said previously in this topic, we would be much better off creating tools to better construct large builds using fxDTSBrick objects. StaticShapes have legitimate application for more dynamic aesthetic elements, but fxDTSBrick can do nearly everything else better and more efficiently (albeit with more objects, but they're made specifically to handle that load).
I will say that this:
The "performance issues" you speak of are nonexistent in real world application.
Is outright false. I've already provided my evidence in the OP, and the history of Blockland can attest to this as well. We purposefully abandoned StaticShapes in favour of the new fxDTSBrick in retail
because these performance issues are very real and very obstructive to the building process, which I think we could easily agree is one of the primary mechanics of this game. StaticShape
does hold the benefit of being a scale-able object class, however for many uses, this will provide unsatisfactory results such as texture stretching. This also is not a catch-all fix for object efficiency, because the collision limitations are still present.
