Is AE Spatial Storage wiped often?

[WhiteDuck]

Really wanting to make use of AE's spatial storage, was going to have a modular base where machine setups were moved about but found out they can't move anything from Thermal Expansion but can move things from MFR so can move mob-spawners and such around.

 

Are AE Spatial Storage dimensions wiped regularly? If they aren't they can be used to store mob grinders and farms and such not in use, mainly for an over-complicated setup just so it looks cool.
