No, while they have a set of old packages because of GPLv3 avoidance, openssh shouldn't be affected, since it's licensed under BSD (it originates in OpenBSD naturally). So it seems more like a neglect of Mer to me. Please file a bug if you can, if not, let me know and I'll file it. There is no point to complain if no one will file any bugs about it. Such stuff should be fixed in Mer really.
