It's great to see people's takes on the idea. I have been mulling something similar. I've bought a couple of old Alphasmart units, which were originally designed to do exactly this: simple word processsors with the ability to dump text via a keyboard interface.

They have a keyboard and standard four line LCD character interface. I'm planning to stick an ESP32 inside and make it dump text via wifi.

After all that, you have to find something to write. I wonder whether having grown up with a random-access word processor makes it difficult to write this way.
