Thanks for your work on this, and for reporting on it here.  Out of
curiosity, who is the "We" involved here?  The changeset history
appears to be a bit ambivalent about the authorship, based on edits to
the README itself:

I'm not convinced that the OpenSSL project should encourage the adoption
of SPECK, given the general level of distrust around the algorithm:


My understanding is that the algorithm designers and primary advocates
have not been particularly forthcoming with their design goals, and
their reputation is mixed, at best.
