Kickstart 3.5

A fake.

Usually these lamers just edit the "3.1" to "3.5" with a hex editor, not even bothering to fix the actual version number in ROM header (40->44 or so).

There is no Kickstart 3.5 ROM. The last one was 3.1 (40.70, which had some problems, so 40.68 was used instead).

AmigaOS 3.5/3.9 "upgrade" the ROM by loading software patches from disk and rebooting the system.

True. That Kickstart 3.2 was V42 IIRC (or was it V43?). We saw the Walker running at Amiga & Retro Computing 2002

However, according to some comments I read somewhere (can't remember where from, sorry), there was absolutely no improvements on it, except the Walker specific parts added to the 2nd 512K rom ($f00000 area, like cd32 and cdtv).

I wouldn't find it surprising if the normal Kickstart ROM was actually 40.68, and only the 2nd chip was Walker specific + custom setpatch to modify the copyright message.

Anyway, I guess we can agree that 3.1 was the final official Kickstart ROM.

Greg Donner's excellent Workbench Nostalgia has some mentions of the Workbench 3.2, although mixed with some 4.0 stuff there.

I thought the Kickstart 3.5 rom was got from uae after being patched with the rom update from os3.5.

You thought wrong.

The patch is software. The ROM image itself is not modified. So if you save the ROM image after OS 3.5 has load rom update, you get exactly the same 3.1 ROM image as before.
