They are still producing those note devices. Samsung, Xiaomi, etc. The interesting thing is that you have something like Xiaomi Redmi Note 8, Samsung Galaxy A50, Redmi K20, all have similar screen size (also all from 2019) and only one of them being called a "note" device.
Honestly, nobody cared about the phablet designation these days. Phablet size becomes normal size and from what I see, currently some people are not asking for normal sized phone but smaller phone like the old iPhone size (5" ish). Basically those 5" phone size is not the norm anymore. around 6" is the current norm.
Also surprisingly (at least for me), not until we reach around 6.7" in diagonal that the current tall devices will have bigger width than the old 5.3" devices. With the thicker bezel in old phones, even Note10+ device width is smaller than the first Note (77.2mm vs 82.95mm).
