LGTM, but can we add a prompt question to the user on the creation flow requiring to the user to set the disk size, putting the tier size by default but allowing him to increase it more explicitly than just sending the param?

Before it was possible to specify multiple volume by repeating the command. eg aleph program create --immutable-volume abc --immutable-volume bcd

But now the syntax changed and it is necessary to use something like --immutable-volume abc#bcd don't know if it is on purpose? The feature before was not documented

Indeed, Fixed!
