Yes, I am currently in the process of migrating over to Win10 LTSC IoT 2021 as official support ends on the 9th Jan 2029 for the 2019 version (non-IoT). So I’ve still got a few years left before I really need to migrate but I might as well do it now to get support until 2032! Most of my systems (laptops & desktops) cannot ‘officially’ be upgraded to Win11 (unless MS do a U-Turn with the minimum hardware requirements!) and I’m not prepared to bin 6 x laptops & 8 PC’s just to prop up MS profits (& they’ll need every penny/cent they can get if they’re gonna flush billions of $$$$ down the bottomless money pit of pursuing the holy grail of achieving AGi). The other reason why I need to move away from LTSC 2019 is that my build has an issue whereby I cannot get Dot.Net 4.8.1 installed because 4.8.1 drops support for older Windows versions. 4.8 supported Windows 7, 8, and Windows 10 versions prior to 2020H2, while 4.8.1 doesn’t and I have some software that will not run without 4.8.1. The IoT version has lower hardware enforcement requirements, so will install without issues on any hardware that already runs Win10. Plus, as it has a lot of the bloat (er… sorry, I mean ‘features’!) removed (& will not automatically receive them in future) it uses less system resources than the bog-standard Win10 builds and is more reliable as a result (as well as running faster). You lose things like CoPilot & all the Ai shenanigans, but I’d say that’s a win-win situation!
Supposedly Microsoft is planning to make big improvements to Windows soon, like making it much easier to strip out Copilot, etc… which is something I myself do. If I am going to use AI, I’d prefer to choose which AI I want to use, especially for privacy reasons. It’s scary how all this stuff wants to access your data to ‘train’ on it, so for that reason I don’t want some kind of built-in AI in my operating system. 
Here is the news from Microsoft itself about the coming improvements to Windows. Hopefully they follow through! Our commitment to Windows quality | Windows Insider Blog
