The 'it depends' answers are good and I would not cite them as evidence of a problem.

They might be the best answers you could get in that company, but it would be better still to get:

"Use this library feature"

"Ok; are there any weird exceptions?"

"No, this is it. We rolled all that company's accounts into this system when we merged, all old accounts in when we upgraded, and planned and designed this to be good enough for the high risk accounts too. There's only a handful of other accounts kept separately and there is no way to verify those from here, by design."
