There's a comparatively "huge" list of devices/images not present in the ToH. 
Not everyone adding device support bothered with adding it to the ToH.

>- There are ~880 devices that are only supported in 22.0x and earlier

Lots of those probably have a working 23.05.2 image. The list in the ToH wasn't 
checked manually. They just ran the usual script. We have no Wiki maintainer 
atm.
<https://forum.openwrt.org/t/help-wanted-wiki-site-admin-managers/175280>

There are 154 devices whose support was dropped with release 23 but(!) this was 
just due to the same earlier decision made to drop 4/32 devices. There were 154 
devices we still built OpenWrt 22.03.x for that officially shouldn't have been 
supported anyways, dropping them was overdue. Noone bothered to do the work to 
drop them earlier.
<https://github.com/openwrt/openwrt/pull/12672> 

My advise:
Don't use the ToH as an estimate it is highly inaccurate.
Look at the download server and which images are present in the available 
releases.
Also: mvebu devices were dropped from OpenWrt 22 temporarily in releases after 
22.03.3, I think. This was due to a bug in Kernel 5.10 regarding their switch 
that was reported after release. They returned with OpenWrt 23. The ToH might 
not reflect this correctly because tmomas script only touches devices who 
received the latest release. And mvebu didn't receive the latest 22 release 
before release of 23.

I would do an estimate if I could. I don't think it's possible to do one 
without building images. Especially since OpenWrt will grow a bit as well till 
any release is done.
But I also wouldn't worry too much about this if I were you :)
