I've already commented on the bug, although I'll reply here as well.
If "-S" is found in bhyve_options it does currently affect both commands. I have decided that a specific wired_memory option is useful though and will add this to the next release.

The name limit has been increased to 32 since v1.2

I didn't realize the changes for cpu topology had actually made it into head, although I don't believe it's actually in a release yet? I will plan to support configuration and display of these before 12 release.
