IOW, I'd suggest some thorough testing to find out how it's actually going to work if it loses and reacquires focus. It would also make sense that exposure lock may not be desired using AF-C (so that the camera could change exposure with subject movement as lighting changes).

So, in addition to determining it's focus behavior, I'd also check to make sure Exposure is even locking with a half press using AF-C (sometimes a translation of how something works can leave a bit to be desired between the camera design and when it hits an English language manual). ;-)

In fact, the only indication in the manual that exposure is locked with a half press of the shutter button, is what I would refer to as an off-hand remark on page 78 of the A330/A380 Manual:

Place the subject within the AF
area and press the shutter button
halfway down.
The focus and exposure are fixed.

That hardly sounds authoritative, especially considering the multiple possible opportunities for misunderstanding you pointed out.
