Nintendo has repeatedly done things like this.
The original Wii supports GameCube controllers, the Wii U supports Wii Remotes, Wii U and Switch both support USB GameCube controller adapters, and NES/SNES Classic Edition Mini systems support the Wii Classic Controller. Switch Lite supports pairing Joy-Con too, despite having no rails for them.
Wii U goes so far with Wii Remote support that Nintendo usually treated it as the preferred way for extra players to join local multiplayer, moreso than its own Pro Controller. Wii games were more limited with GC controller but still supported it in a few big titles like Brawl and Mario Kart Wii.
The 6-month release cycle makes the most sense to me on desktop. Except during the times I choose to tinker with it at my own whim, I want my OS to stay out of my way and not feel like something I have to maintain and keep up with, so rolling (Arch, Tumbleweed) is too often. Wanting to use modern hardware and the current version of my DE makes a 2-year update cycle (Debian, Rocky) feel too slow.
That leaves Ubuntu, Fedora, and derivatives of both. I hate Snap and Ubuntu has been pushing it more and more in recent years, plus having packages that more closely resemble their upstream project is nice, so I use Fedora. I also like the way Fedora has rolling kernel updates but fixed release for most userspace, like the best of both worlds.
I use Debian stable on my home server. Slower update cycle makes a lot more sense there than on desktop.
For work and other purposes, I sometimes touch Ubuntu, RHEL, Arch, Fedora Atomic, and others, but I generally only use each when I need to.
