> other CAs aren't prohibitively priced

Not if you look at the per-cert pricing, but if you factor in the cost of "dealing with incompetent sales" and "convincing accounting to keep the contract going", they absolutely are.

When I was working with Digicert a decade ago, it was expensive, but they also had knowledgable support and with a wildcard cert, they would issue all sorts of 'custom duplicates' by request that were super handy. No incompetent sales, but certainly you do need to make sure accounting will pay.
