jail -n <jailname> is there for a long time. I have it on an old 7.3
machine too.
On 9.1 I read this in man page:
-n jailname
Set the jail's name. This is deprecated and is equivalent to the
name parameter.
So in 9.1 (and 8.x) you can use `jail name=myjail`
And as 7.x is EOL, there is only 8.3 and 9.1 as supported releases (9.0
EOL date is 2013-03-31), you can go with name=myjail syntax.

Jail's hostname doesn't need to be unique. And AFAIK jail name on
FreeBSD 7.x doesn't need to be unique too. But for 8.3 and 9.x it is
used as unique identifier.
If name is not set, it is assumed to be the same as JID.
