Adding an option to triangulate meshes in the exporter wouldn't that
much of a trouble (though it would have to wait for after the 2.78
release), but I have to ask what prevents you from triangulating the
meshes before exporting? If you've got a lot of objects to triangulate,
a simple Python script can be written to automate the process. Shall it
be a destructive operation, or shall it preserve the state of the meshes
(meaning meshes in Blender are not triangulated, but the exported ones

For the axis conversion, Alembic files written from Blender follow the
Alembic Y-up convention, so I guess this is already what you want? I do
plan on adding support for more (custom) axis conversions though.
