scp in openssh 8.7 will change to use sftp protocol. See
https://github.com/openssh/openssh-portable/pull/194 for details.
This enables the sshd internal-sftp implementation so that newer scp
versions will continue to work as expected. Note that the sshd service
is only running during the installation if inst.sshd is passed on the
kernel cmdline.

Some of the options have been removed, others are now the default.
MOTD still needs to be printed, the boot environment doesn't include the
pam motd module.
