They were introduced when MEMROY_AREAs and VAD still lived in different tables to synchronize between them. Since some time MEMORY_AREAs are special VADs and live in the same table as ARM³ VADs, but with flags to distinguish them. Since then the only reason that the fake MEMORY_AREAs still existed was to determine whether a VAD that is a MEMORY_AREA is still handled by ARM³ (which is the case for some kernel VADs, like for paged pool). This is no longer required as it is now determined by a 2nd flag in the VAD itself. Additionally, we tried to insert the fake MEMORY_AREAs into the VAD table, which would fail, because it was already occupied by the ARM³ VAD, but the failure was ignored.
