Debian Trixie, to my knowledge, comes with Linux kernel 6.12 LTS. Many people with more modern hardware want the most modern Linux kernel -- currently 6.18 -- to support their devices. There are also countless stabilization patches (I heard some of my acquaintances praising their Linux kernel upgrades as finally giving them access to all features of various Bluetooth periphery but did not ask for details).
Having a modern kernel is important. With Debian though, it's a friction.
Can it still be done? Sure, or at least I hope so as I want to repurpose my gaming machine as a remote worker / station and the only viable choice inside WSL2 is Debian. I do hope I can somehow make Debian install a 6.18 kernel.
Furthermore, you putting the word "need" in quotes implies non-determinism or even capriciousness -- those two cannot be further from the truth.
Arch and Fedora can't come to WSL2 soon enough.
...and none of that is even touching on the issue of much older versions of all software in there. I want the latest Neovim, for example. For objective developer experience reasons.
Debian stable is for purists or server admins. Not for users.
