I respectfully disagree.  I asked a follow-up question to which there
has yet been no reply, and I think that all concerned would benefit
from a clarification of the issue.  I repeat it below, together with
subsidiary questions that may need to be addressed before the situation
is fully clear :

The subsidiary questions are : once XeTeX has been linked into
Libkpathsea, do they then form a monolithic whole ?  In other
words, if I receive from Jonathan XeTeX.exe, does this .exe
include Libkpathsea, or does it simply make reference to it,
which reference is satisfied at run time ?  Because if XeTeX.exe
/contains /Libkpathsea, then I would expect the licence for
Libkpathsea (and any other analogous components) to have to
be made explicit; whereas if XeTeX.exe is just a stub, which binds
at run-time to Libkpathsea, then I can see no need for the latter's
licence to be made explicit because Jonathan is not distributing
a copy of Libkpathsea, merely a reference to it.
