The article in the June 2018 Watchtower, the following is the first paragraph, highlights are mine

No doubt you have often used a greeting such as that. You may even have accompanied your greeting with a handshake or a hug.

In fact, not offering or responding to a greeting may be taken as unloving or as evidence of bad manners.
Poopie, it's very unlikely that there will be any change in policy.
