Where is the zfs option?

[hput]

I'm in the middle of an install of 22.04 on hardware.  I've done a
number of ubuntu installs and even a few of 22.04 on vms.

I always see the zfs option early in the install at the Advanced
features stop.  But this time when I click on the advanced features on
the left, the right side opens up and offers a button to chose:

   "use LVM with the new . . ."   Can't read anything after `new' just
   dots.

But isn't this usually where I should be getting a choice of `zfs/?

The install media is from the daily build of 22.04 at:

   https://cdimage.ubuntu.com/daily-canary/current/

can anyone explain to me what is happening here.  Has Ubuntu dropped
the zfs option in the newest daily builds of 22.04?

The 22.04 daily build I install to a vm about 4 days ago offered zfs
where I expected it. 

Or has the option just been moved somewhere?  I'll keep going to the
point where I wouldn't be able to back out and see but I alread went
on a few a few clicks and I didn't look promising.

Ok, I've looked far enough ahead to see I'm leaving the possibility of
setting up zfs behind.  So what is the deal here?

Is there another list where I write directly to the people who do the
daily builds of 22.04?  I'd really hate to loose that zfs option.
