@zoomer I must admit, I was heated and rushed posting this. Afterwards, I did some reading around the forum and have since lost all hope that VW will ever support Metal.
From what I've gathered, Vectorworks is as incredibly bloated and inefficient as Microsoft Office. It uses far more resources and lines of code to complete tasks than necessary in today's modern operating systems. Much of this code is probably very old—which is why it is taking the engineering team so long to switch all tasks to the new VGM (which utilizes graphics cards and Direct X over slower CPU processing).
While I don't think they will use Metal (or fast DirectX on Windows) soon, coding for the lowest common denominator a big mistake. This is why I choose iWork apps over MS Office, Pixelmator over Photoshop and so on... Eventually, another company will take the day's current APIs and create an app that matches or surpasses while using far less resources and making users much more happy.
Unfortunately, this is a long way off for something as complex as Vectorworks. Hopefully the day will come when they throw out their aging code base and reinvent the program from the ground up, a-la Final Cut Pro X. Computers will continue to progress and eventually, developers won't be able to disregard technologies like Metal. These advances are key as processors become smaller and more mobile. Over time, doing more with less becomes a requirement, not a hope.
As of now, the biggest push to do more with less is coming from Apple—in both hardware and software. It has already afforded them a sizable processing and graphics lead in the mobile space. There is no doubt these ways of thinking (headlined by their use of custom CPU designs) will make their way to laptops and then to desktops. Computers, as they are now, will be relics in 10-20 years... and this VW code that has been slowly siphoning time from our short lives will be stone-aged.
I definitely see where Apple lost their way with professionals for a time, but I already see that course being reversed. In my profession, Macs still outnumber PCs 5-to-1 because even though they could have been better at supporting pro workflows, there is still no question that they remained the best. The few people I've seen switch spend their days wanting to throw their PC laptops off a balcony.
I know that one could take a Windows desktop, throw 500W of graphic card power at it and nearly rule the world. That may be great for anyone whose workflow keeps them at a desk, in an office. For my needs, programs like Vectorworks need to be fast, reliable and powerful while on the road—sitting in an airport lounge, a hotel room, on an airplane or a live production set. If VW wants their product to kill it in the office and on the go, they need to think about supporting the technologies that can make that happen.
I'm not holding my breath, but I'm also not wrong in asking. Vectorworks should support the top technologies of every OS. They should make their product the best it can be everywhere it is used because this is what we pay them to do.
