I think you're correct, that these will become more common. A couple of years ago I was chatting with friends who were doing APIs, because of market/regulatory pressure EU's PSD2, exporting JSON of transactions using COBOL for use in online. Because that bank - almost an order of magnitude larger than First American in terms of employees - will do everything in order to not move off COBOL / it's legacy system.

Interesting skill set: COBOL, DB2, JS, Angular.
