In a way yes, because I would expect a second pair of eyes looking over those.
Over the years I have seen many Excel "applications". I have even seen a closed loop simulation in Excel - albeit only with fixed step solver.
They all had one thing in common: The were perfecly good when they were working. However if somebody inserted a row, broke a link or Excel would not update a cell for some unknown reason (which I have experienced) they would fail - and the failure could only be discovered by critical awareness of the individual before the screen.
Add the possibility of these copy and paste errors as we've seen here.
So yes, perfecly inadequate for loadsheets.
QED
