He Kenneth,

Many thanks for the summary. Just to clarify that my question wasn't why 
the team decided to implement JIT instead of fixing HiPE going forward. 
I was interested why did you decide to abandon HiPE 10 years ago and 
instead put effort into JIT. 6 man months sounds a lot but from the 
presentation it looked like a similar amount of effort was being poured 
into JIT since as early as 2012, which coincides with the time when HiPE 
apparently stopped being actively supported.

This is not to judge, or criticize, or to play what-if. I am just 
curious about the reasoning, if there is any, to learn something about 
both technologies.
