OpenWrt only releases updates for two years after release. The project doesn't profit from super long term support.

That kind of depends on how you define the minimum 😅
I don't consider OpenWrt bloated. Sure you can go the extra mile to thin down the kernel further but that should be left to people doing their own builds anyways. Though this going offtopic

I'm curious when OpenWrt will loose devices with 6MiB of available space.
For the ones with 7MiB (close to 8MiB) I don't expect kernel 6.6 being too large, so hw isn't moving into obsolescence any faster. Sure the next LTS Kernel afterwards might arrive a bit faster but that's a very positive thing for most devices so they get the best kernels during their expected lifetime.
