Setting multiple values in one turn

From semantic-mediawiki.org

Dabbling a little bit with some old templates of mine I found out that

{{#set:
 |property1=value1|value2|value3
 |property2=value1|value2|value3
 ...
}}

can be used to store multiple values for one property. Since I did not find any mention of it as I wanted to confirm this, I would like to ask, whether this is a solid feature (and remains so) or is it unwanted and will be removed somewhen?
