Read host keys from environment variables

Hi everybody,
for use in containers it would be nice to pull SSH host keys from
environment variables.
So, as an example, with an environment variable similar to
HOST_KEY_RSA="-----BEGIN OPENSSH PRIVATE KEY----- b3Blbn…AwQF
-----END OPENSSH PRIVATE KEY-----"
(general whitespace, so "\r\n\t " being allowed) I'd hope for an
sshd_config saying
HostKeyFromEnv HOST_KEY_RSA
being enough.
I saw "HostKeyAgent", but providing a unix-socket to a different
container
running an agent with the keys is more complex and more likely to fail
than
using environment variables.
sshd could even be so nice as to drop these variables from child
processes,
although for my sftp usecase it shouldn't matter.
Thanks for any feedback!
Ph.
