On the other hand, all alphanumeric LCDs are almost certainly going to have a controller with the same or nearly the same instruction set as the infamous HD44780.
Nonetheless, longer single-line sizes than 16x1 are not entirely nonexistent; here's someone who has a 24x1:

Here's a few other 32x1 I found:

(One of Google's most noticeable degradation in search results is when searching for parts like this. I'm sure there are plenty more sites where a 32x1 character LCD can be found, but it's just not returning them.)
This. Reverse engineering character LCD displays is bit-banging your way around the HD44780 specs and see where you land.
So it would not be terribly surprising that other competing controllers also support it.
It's not just parts like this, it's pretty much all parts. Search results are massively front loaded with SEO farms 'selling' something that is vaguely related to the search term (all of whom don't actually stock the part). Getting actual information about the part, a blog post about the part, or finding someplace it's in stock, is increasingly an exercise in frustration.
It's amazing how doing something repetitive and "zoned out" like this can clear your head and make room for fresh breakthroughs. I spend a couple days plugging gaps in my work schedule by sanding custom furniture I made, and felt slightly more productive each time I went back to my desk afterward.
As a side note, the text on the chip when photographed at 200x appears to say “VIA-AEPT-A CHP-A” when you turn the image upside down :). https://imgur.com/a/4BpivfH
I have a old clock radio in a box which I was thinking to turn into a internet/podcast radio at some point (so I could always get the news right when I'm supposed to wake up)
I was planning to retrofit a piTFT or something into it but it would be much cooler to reuse the existing LCD... although based on the amount of work required and history of me completing these "interesting" projects I have on the shelf... I will probably do neither and at some point just buy something suitable :-)
