So, I gave it a spin and had to fix up something already ;)
I built commit 5ee246b1084d6679f3fc5d624dd5fb64456e8aff with the
following patch applied:

You forgot to install the new file ;) and the install location
is bogus anyway, this needs to be moved to /usr/libexec/ifupdown/
instead (globally).
Here€€€s also the lintian warnings, most of which should be easy
to fix:

With this, the interface does indeed come up, wait, and
I get the expected IPv4 address€€€ but not the expected IPv6
address:
3: wlan0: mtu 1500 qdisc noqueue state UP
group default qlen 1000
link/ether bc:cd:99:00:3d:18 brd ff:ff:ff:ff:ff:ff
altname wlp2s0
altname wlxbccd99003d18
inet 192.168.0.208/24 brd 192.168.0.255 scope global dynamic
noprefixroute

mngtmpaddr noprefixroute

valid_lft forever preferred_lft forever
inet6 fe80::becd:99ff:fe00:3d18/64 scope link proto kernel_ll
valid_lft forever preferred_lft forever
This is a regression to ifupdown in trixie, where I got the
expected EUI64 address.
- 2001:470:1f15:10c:7922:456f:9923:7a9e €€€ completely bogus,
breaks reverse DNS, firewalling, etc.
- fe80::d658:47f3:7d84:b5e €€€ even more bogus, why is this
even on this interface, it€€€s not related to any of the
other addresses (IP or MAC)
- fe80::becd:99ff:fe00:3d18 €€€ correct EUI64 link-local
For completeness: the interface wlan0 is not listed anywhere and
was brought up by €€€sudo ifup wlan0=mywlan€€€ with:
iface mywlan inet dhcp
wireless-power off
wireless-essid mywlanssid
wpa-ssid mywlanssid
wpa-psk mywlansecretpassword
Awaiting your next roundd of fixes,
