Remote activity with verb 'make-friend' and 'like' ignored

some activites do not appear in my statusnet (I use SubMirror to import them)

!statusnet tells me: Ignoring activity with unrecognized verb

e.g. for verbs: like + make-friend (1)
I understand the reason for "make-friend" because of note in (2):
"...processors MUST NOT accept activities with this verb unless they are able to verify through some external means that there is in fact a reciprocated connection."

but from what I read there "like" should be possible, or not?
"Indicates that the actor marked the object as an item of special interest. The "like" verb is considered to be an alias of "favorite". The two verb are semantically identical."
and "favorite: Indicates that the actor marked the object as an item of special interest."

Is this because it's a draft and it's not yet implemented?
