Piotr, what do you think about adding the check to the udev script
instead of bloating cryptroot script with yet another delay?

David pointed me to the fact that the proper fix would rather be to fix
the udev initramfs script, not to add yet another delay option to
cryptsetup initramfs script.

The udev ROOTDELAY implementation already is at the right place, it just
needs to be extended to actually check for existence of the device.
