It's most likely a strategic demand for finding a diplomatic solution in the middle at the end.

One side isn't really in favour of sending the cruise missiles and the other side strategically demands, what will most likely never be agreed upon. Then discussions, expert questioning, manufacturer feedback, analysis, more discussions... At the end everyone agrees somewhere in the middle. E.g. to send them, but the same way as France and the UK already did with reduced range and agreed countries to target.
