Initramfs wants to start ATA-over-Ethernet before mounting local (!) root partition

Question

I'm on 22.04 and just did a dist-upgrade to upgrade some helt-back packages, which went through fine. However, my boot now seems to depend on acquiring a DHCP-lease on my ethernet interface. (Side note: I also have a wifi-interface which aquires a lease just fine, but that's not the point. My boot should never ever block if I don't have network, unless my root filesystem was on a network mount, which it is not).

Here's an extract of my dmesg with comments:

[...]
[    1.767795] usb 1-10: New USB device found, idVendor=8087, idProduct=0033, bcdDevice= 0.00
[    1.768998] usb 1-10: New USB device strings: Mfr=0, Product=0, SerialNumber=0
((COMMENT: onscreen I see the following here, but it doesn't show up in dmesg:
Begin: Loading essential drivers... done
Begin: Running /scripts/init/premount... done
Begin: Mounting root filesystem... Begin: running /scripts/local-top... Internet Systems Consortium DHCP Client 4.4.1
... lots of messages from DHCP failing to get a lease on my ethernet interface until I plug-in a cable...))

Looking at the screen-output, it seems that the initramfs does indeed think that my root partition might be on the network because it doesn't say "done" after "Begin: Mounting root filesystem...". What's going on?

EDIT: my /proc/cmdline contains BOOT_IMAGE=/boot/vmlinuz-6.5.0-28-generic root=UUID=0a928e5f-d8c1-4b2a-9d12-b6d814efcf42 ro apparmor=0

Researching a bit, it seems that my initramfs-tools has an "aoe"-hook skript, probably because I am actively using ATA-over-Ethernet, just not for my root partition. Further there's a script /usr/share/initramfs-tools/scripts/local-top/aoe which calls a bash-function configure_networking and that one seems to be the culprit. I don't fully understand that function, but I think it's supposed to be used when the root is on an NFS-partition and, since I didn't configure any NFS-related things for my initramfs, it frantically tries to get all network interfaces up before attempting to mount the root-fs. I suppose a bug-report is in order...

EDIT: For future reference, here's the bug-report.
