+1. 

To aid in the analysis, I copy/pasted the Table of Hardware into a spreadsheet to see what we would be losing. I started with https://openwrt.org/toh/views/toh_extended_all

The resulting spreadsheet is at: https://docs.google.com/spreadsheets/d/1j_Yv62tdYzvA4iU216W3B0XHswXv2U2LrxQ0QOB5-vE/edit?usp=sharing

The tabs are:

- Original Data - as copy/pasted from the Table of Hardware. Cells are protected to prevent inadvertent changes.
	The rest of the spreadsheet is unprotected and you should feel free to modify it/make new tabs
- Sorted by Curr Release - same data, but sorted by Current Release column (Column I)
- 23.0x-only devices - removes the rows for 22.0x and earlier, and current release = blank
- Changelog - changes from original data to produce current state

Observations:

- There are ~2200 devices listed in the ToH
- There are ~880 devices that are only supported in 22.0x and earlier
- There are ~330 devices that have the empty string as the Supported Current Release
- Virtually all the devices in the last two items (22.0x and earlier, and empty string) have been discontinued/unavailable from before 2020

Can someone who knows more about our devices make a judgement whether we would lose an appreciable fraction of devices by switching to a kernel that might not fit/work? Thanks.
