Not really since there is little chance for this to work well without additional software which likely would limit its functionality, also it doesn’t seem to matter that much for a couch keyboard and if you want smaller there are smaller keyboards.

Why? If it's done in any sensible way, it should simply show up as a HID device and work pretty much everywhere.
Because these types of trackpads need special drivers these days e.g. windows precision drivers.
Even basic things like palm rejection is done in software and for this one to switch between keyboard and trackpad in the fly you’ll need very good software that can predict just what you were intending to do.
Most "windows precision" touchpads are handled in Linux with just one module. Even Apple's Magic Trackpad can show up in system as a regular mouse (although with limited functionality).
Palm rejection is a thing that kinda makes sense to handle in software. For this thing, I'd expect firmware to be actually a bit beefer than usual.
