They were almost certainly referring to the winter & electricity gear. Unless there's something undisclosed, but I don't see that given that Ukraine still lacks a launch platform for Taurus.
They managed to adapt the Su-24 for Storm Shadow, no reason it couldn't be done for Taurus; they are of similar size and weight.
I think the compromise was that they need to be programmed on the ground, as the aircraft avionics don't offer a compatible complex interface, but a launch signal can be rigged. Since Both will probably be used against fixed targets (airfields, bridges, ...) that is not a big drawback. Still, it needs to be done, and is not quite trivial.
I think Stormshadow is pre programmed by UK staff on the ground first before eventually launched by Ukrainian pilots. That won't work with Taurus afaik as it needs a constant connection to the plane and also I believe it is also illegal for Germany to have their troops involved directly.
