No lastCompletedBuild symlink

I maintain few jenkinses, various versions (2.x). Some of jobs on them publish artifacts even when build result is failure. Using jenkins UI I can access artifacts via http url

JENKINS_URL/job/jobname/lastCompletedBuild/artifact/file.ext

But I need to access this artifact directly from filesystem where artifacts are stored, in my case it is custom path:

/mnt/jenkins/builds/jobname/lastCompletedBuild/archive/file.ext

On disk, lastCompletedBuild symlink is not created. I still can access the file, but I have to know build number. The same is for lastBuild. To sum up: it works for lastCompletedBuild, lastUnstableBuild, lastFailedBuild, lastUnsuccessfulBuild. All shorthand urls from job page have their respective symlinks created, except lastCompletedBuild.

Is it intentional?
