It was introduced to mitigate errors being encountered as being described in issue #1306.1 The configuration parameter was introduced in Semantic MediaWiki 2.3.1Released on an unknown date unknown versions of MediaWiki.2

The setting of this configuration parameter should not be changed unless issue #1306 is being encountered1 due to the following note: "... libcurl to use the specific HTTP versions. This is not sensible to do unless you have a good reason."3
