I guess it is to prevent creating lots of small "islands" of support on some prints. Since PVA does not stick very well to PLA, these would have a larger chance of tipping over. And it should not do much harm because it will dissolve anyway.

Thx, found it.
Any benefit from having that expansion when using PVA?
(Value came from the built in profile for Generic PVA)
