It looks as though, to make the framework taller to support keys with travel, you'd need an entirely different case -- but so long as the mountpoints for everything were otherwise the same it seems like it wouldn't be a radical rework of the product.
One can imagine a double thickness framework with either somewhat bigger battery and mechanical keys or super huge battery and the smaller keys; and of course more (or at least larger) expansion cards.
But of course the idea for something is worthless - it's the execution that matters. I hope they succeed enough to be able to expand their portfolio to more niche markets.
There's nothing like the feel, and my RSI issues that I was starting to get improved greatly not bottoming out on a sponge for every key tap.
Unfortunately, switched keyboards for laptops are limited and don't have much travel... they do exist and are definitely superior though. Would be a cool option for framework, but not sure how well they fit for clearance, or what kind of switches framework's kb uses... I've been using an M1 air that I had bought before hearing about framework for personal use, but don't use it much... in a few years, will likely buy from framework and hope they're still around.
