Why is part 87580 called Tile 2 x 2 with Groove and 1 Stud? I feel it should be Plate 2 x 2 with 1 Stud to be consistent with Plate 1 x 2 with 1 Stud.
Not sure I agree. It is more tile than plate by three to one.
Although by that argument 6576 should be a tile too and arguably 88000.

Although that discussion misses the myriad of other parts (official or otherwise) that have both tile and plate qualities. Where 88646, 6179, 6180, 4607, 4522, 6178, 6205 and 6177 (+print) are all considered tiles.
Overall it seems that de facto standard is that if you have more flat space than studs you should really be a tile.
That said, Orion's point about 'jumper plate' makes sense. And 87580 is probably becoming known as a 'double jumper plate'.

I used the standard of:
I was confused and couldn't find 87580 part for a while. If I was confused and I'm probably one of the most advanced LDraw users then I'm not going to be the only one.
Until you pointed it out I hadn't noticed they were split apart as I always go looking for the jumper plate in tiles.
Categorisation is never going to be perfect for everyone but I do agree with you that the jumper _plate_s should be plates, if only for historical and common nomenclature reasons.
Although I also think 88000 (definitely) and probably 6576 should be tiles.
