This is only needed on systems where initramfs.conf(5) sets KEYMAP="y",
but maybe it's not so easy to determine as mkinitramfs *sources*
/etc/initramfs-tools/initramfs.conf, /etc/initramfs-tools/conf.d/*, as
well as /usr/share/initramfs-tools/conf-hooks.d/*, and the ‘KEYMAP’
variable can be set in any of these.  cryptsetup-initramfs' own
/usr/share/initramfs-tools/conf-hooks.d/cryptsetup sets it for instance
(override settings in /etc/initramfs-tools).

The initramfs-tools maintainers will correct me if I'm wrong but AFAIK,
for that to work the set of keymap(s) to choose from needs to be copied
to the initramfs image.  At init-top stage we can't rely on any device
holding data from the main the system (/boot, /, /etc, etc.) to be even
present, let alone unlocked or mounted.
