Removing SQL Server Native Client 2012

Sean Gallardy answers a question:

I see many questions, and have been on the receiving end of many myself, about out of support items and removing them from their SQL Server servers. One of these items is the SQL Server Native Client, aka SNAC, aka SQLNCLI, and I’m sure many others. I remember investigating the connections a very long time ago when availability groups first came around (2012) and haven’t looked at it since that time. A question on the database administrators stack exchange asked the question about if SNAC could be removed on a SQL Server 2019 instance used in high availability and my gut reaction was, “nope.” Gut reactions are great but not always correct, so I did a little testing.
