Not sure if "the stability of the system perl suits me better" is intended to cover this, but:

- the cost of potentially introducing new bugs far outweighs the benefit of (this list of) new features;

- last time I upgraded everything broke, I don't want to do that again.

The first of those pretty much covers the perl I use for maths research - it is currently running on 5.34, but I tend to upgrade it very rarely. If I find a bug that affects my maths results, I potentially have to rerun tens of CPU-years-worth of calculations. (Last time that happened I was lucky that I had just moved to a much faster new computer, so it only took 6 months to recompute the previous 10 years of calculations.)

The second covers a couple of companies I used to work for.
