This is for SSL and certificate validation - Google's move won't affect git in any way. Git uses it to ensure that the data that comes out is exactly what went in (like a much better checksum than md5 or crc32 etc). I don't know what the security implications are on the git side... I suppose an attacker could try to figure out how to change source code in a way that it preserves a commit log.
