Yes - for the simple reason that from January 2017, Google Chrome will start marking all sites that do not have https active on sensitive pages as insecure - this is a very important step.

"Eventually, we plan to label all HTTP pages as non-secure, and change the HTTP security indicator to the red triangle that we use for broken HTTPS."
So really, you have no choice, and honestly, it's not so bad. We just moved our entire site to https without any issues.
