What is purpose of V-shaped cutout in LED's pad?

[ocset]

Hello,
What's the purpose of the V-shaped cut-out in this LED's pad? (Z8Y19 LED) Is it to help it sit centrally on the pads when its being reflow soldered?

The footprint is seen on page 21 of the datasheet

We have 200 PCBs where we forgot to put the V-shape in...must we throw them in the bin?
The ones we tested work well and the LEDs look perfectly central, even though we forgot the V-shape.

I would think it is more to help denote which pad is the cathode.

Probably just for polarity (assuming you don't have space to do so on silk).  Outside chance it reflects the part metallization, but yeah, it isn't going to matter, not at this scale anyway.

Also if it were intended, there would be dimensions.

No need to include the cathode indicator on the board.
