Assuming no one yells about it, I'd like to request that the Cygwin package repo maintainers check for packages that still have libexpat0 as a dependency, and if none are found, remove it.
When I took over maintainership of the Cygwin expat package, I asked
that this older ABI version of the library be kept for programs that
need it, but that was four years ago now. It's still there.
