The reliability issues are the only ones I can think of, but especially in the following sense:
* If only you have A->B and B cannot be reached while running a query from A, the query result will contain a warning about that which will also be shown in the graph UI. * If you have A->B->C and C cannot be reached while running a query from A, that warning doesn't make it all the way back, so you just get an empty result set without the warning.
