By the way here's a nice factory tour if you haven't already seen it:

V-scoring room is at 22:00
Also, have you thought of using just normal milling + mouse bites?

Does that mean V-score along the outlines of the 100x100 mm area?
Or does that mean V-score INSIDE the 100x100 mm area?
Does that mean ONE V-score or several?

PCB fab will mill outlines of 100x100mm area (lets call it panel), V-score lines are inside.
V-score cut wheel can not stop in the middle of a panel, so the cut must go throught whole panel from one edge to another edge.
They will do multiple V-score cuts in both directions if needed. I have no idea if they do also cuts with arbitrary angle to outline.
I ordered yesterday a batch of 25x30mm boards (isolated USB-UART bridge) with 5mm rails and got it approved today.
Panel size is 4*25=100, 3*30+2*5=100.
Actually it is just to test this service. I do not need so many boards.

I doubt they would do more than perpendicular. Most odd shapes then require milling and/or combination of milling and V-cuts, but V-cuts should be perpendicular to the board / panel edges.

Inner corners can not be perfectly rectangle, because milling cutter has some radius/diameter. But why on earth they are talking about plated slots?
Do they think, that outlines of your boards need to be plated? This might be the case, since the milling lines (light blue) go to copper on rails and there is no proper clearance between copper and slot (see attachment).

Yes, I started also thinking weird things, that´s why I contacted them with a second e-mail, still waiting for an answer though (it was one hour before their closing time to be fair).
I told them that I kept the dimension layer of each individual board to handle the copper pour pull back, but where they have to V-cut and mill I have already designated in the respective layers.
I proceeded with the order never the less. BTW in the first email they sent me a picture of the gerber files as they see them. And from that point it was kinda reassuring.
And if for whatever reason they plate the edge rails where they are cut, that´s not really a concern for me. I just did not want to be an a$$ with their etchant.
I´ll include the photo they sent me below.
