I don't understand why you want to change the default. Is it for performance? Has it been measured?
Yes. I've run into it multiple times, but I haven't specifically measured it. But I've had more than one situation where turning it off has completely removed a performance problem.
I've only seen it in apps without proper connection pooling. It's the negotiation of new sessions that's expensive, not actually encrypting the data.
Most people definitely don't run into it, because most people don't use localhost when they're local - they use the Unix socket. But for example a locally running java application will be using localhost.
