Okay, sure, typing accents with this type of keyboard may be worse than what we currently have on smartphones. But as I mostly write English this would not be a huge problem to me, otherwise in German there are only äöü/ÄÖÜ and ß/ẞ which don't get used that much, but have extra keys on the German keyboard layout (I don't expect this to be the case on a keyboard phone). Or can be replaced with ae,oe,ue and ss respectively.
Auto-complete/-correction is something that I don't use often, but this doesn't need to be missing from a keyboard phone, as this could be added on the software side.
Emojis are also something that I don't use often, but I get it that people may miss this, but this could also be added on the software side.
I have something similar to the BlackBerry Key2 in mind [0]. Haven't tried it myself, as I just learned about this through the comments. But the keyboard layout on the Key2 looks way better than the Unihertz, and the numerical keys are even in the same layout as a numeric keypad.
I may as well have too many rose-tinted memories of this era, but I don't think that the things you mentioned would be showstoppers for me, but I definitely can understand that these will be blockers for other people.
