In the absence of any show attribute, the behavior is unconstrained by
XLink. This does mean that such links may not behave in uniformly
interoperable ways, though I imagine that most applications will treat
absence as synonymous with 'other' or 'none'.

I don't disagree, but amending the semantics for show and actuate are
outside the scope of the XLink 1.1 effort.
