Comment by James Wahlin [ 24/Nov/20 ]

This feature has been backported to 4.4 and will be available in 4.4.3. Please note that while the backport introduces a mechanism to enforce a length limit, it sets the default very high. To make practical use of this in 4.4, the limit should be lowered via the 'internalPipelineLengthLimit' setParameter.
