Viable filtration and VOC monitoring for the XL?
Will we see a good solution for HEPA and activated carbon filtration?
What about an air quality monitoring system, which could even use the lighting system of the cabinet to flash colored alerts (orange, starting to get bad; red, over recommended levels).
VOC and TVOC monitors are getting cheaper, but to get a quality reading at an affordable price requires long term monitoring of 1-4 weeks (this is not a problem for most 3D Printers which are typically in the same place most of their service life).
Obviously for this filtering to work, they would have to offer an enclosed cabinet. Between the SL1 and their Delta venture, they are starting working more with enclosures. Once enclosed, I'm curious what level fan would need to be utilized in order to filter the space and the mechanism around easy maintenance and changing out the filters.

Would be really needed for commercial operation... SL1S has it too...

If it has a hook for I2C it could easily be done with adding some hardware. I2C PMS7003 for particles, I2C VOC detectors are cheap as well. It could autodetect them at boot.
(I'm hoping to be able to control the lights and read printer data from home automation.)

I've been looking for an off-the shelf solution for this in a printer for a long time, it would be really great. It's the only thing missing (or to be confirmed) to make it a perfect printer for my application

Google reveals some solutions - they are pricey.

There are more and these are just a few.

As you can see from @cwbullet's reply, if you want effective filtering you will be laying down a lot of cash. The best budget solution is to create negative pressure in the enclosure that is vented out a window or exhaust port in the room. As long as you sustain negative pressure in the enclosure you do not need to completely seal it. A little bit of airflow into the enclosure is required to allow the VOCs to be exhausted out of the enclosure.
For my MK3S I cut a hole in the side of an acrylic enclosure from 3D Upfitters and mounted a 120mm fan to blow into a dryer hose and out my window. Sure, it throws VOCs out into the world, but I don't have the means to properly capture and dispose of those things with methods mentioned above which would routinely cost me hundreds to replace the filter after buying an already expensive device.

With VOCs, this is probably a 90% solution. It is hard with a semi-sealed enclosure to get good negative pressure. This is probably good enough.
