In further support of this theory, neither my continuously-upgraded
unstable system nor my continuously-upgraded testing system have that
file. The testing system was built in 2014; the unstable system in late
December 2017 (so that may not be as interesting). (Neither of those
hosts are using merged-/usr, just to say explicitly.)
I think that argues that there was some cleanup step that happened for
some systems but not for others.

This also implies that there is arguably an SONAME issue with this library
given that two versions of the library with the same SONAME don't provide
the same symbols, but I suspect there were really, really good reasons to
not change the SONAME.
