We don't have any plans we can share yet, but we did design the display to be easy to replace by putting it behind a magnet-attach bezel and using fasteners to affix it the lid.
Are you considering OLED as well? The Dell XPS has that as an option and it is a serious draw, especially for coders who stare at a mostly-black screen all day.
This might be a bit much, but if you offer an e-ink with the same interface as the laptop, it would be very cool to have an external usb-c case for it. So people can choose which display for their "main" monitor, and have the other one as an external portable monitor.
It would depend on your meaning. If you mean taking a device like a Dasung or a Onyx and connecting to the laptop and using it as another screen, then sure, that should work fine. If you mean taking out the LCD and popping in a raw eink panel, then no because they have different interfaces. Speaking of which, I don't see any clear specification on frame.work for the LCD connector or power specs.
I see they wrote on their blog.

We don’t currently have plans for alternate displays, but we’ve designed the display to be easy to replace and the display connector on the mainboard to be able to support a broader range of possible displays. It’s unlikely we would go lower resolution in this form factor, but I agree there could be an interesting case for a display resolution that works at 2x scaling (at the tradeoff of battery life).

But I couldn't easily find on their website the info for what type of connector and what type of power is delivered to it.
No matter how much you qualify an answer: “yes, but it’s extremely early in design, we may not be able to find the right manufacturers so it may not happen at all, but the earliest possible date would be late 2022”, there is a segment of people that will have an expectation that you will deliver the product before 2023 and will be upset if you don’t.
That is right. I’ve answered a few questions in these comments where the answer is basically: It’s technically possible, there is a plausible market need, we think it is worthwhile to do, and we’ve designed for it architecturally, but we can’t commit to a specific date because there are always implementation risks, supplier risks (especially this year), and a large number of programs we have to prioritize between as a small team.
