Looks pretty good. I have a dumb question though, for which I haven't
found an answer - how can I enable/disable readahead? I haven't checked
in Rawhide yet, but in F10 it is not among services.
It's explained in the test cases, I think? I'm pretty sure I remember
writing it there.

You edit /etc/sysconfig/readahead , the first line is the key. The
advice to enable / disable it as a service, in the old version of the
test day page, was presumably outdated.
don't forget to:
# touch /.readahead_collect

after you active readahead to trigger the data collection.
Reboot for the data collector and reboot again after a full boot.

...well, that was completely obvious!

so my results which I did with two reboots but *not*
with /.readahead_collect would be invalid?

Well, yes, if you didn't reboot after installing readahead without turning it off.

I added the command to the wiki pages, yesterday.
