I suppose nobody took note of it because it was a reply to a topic with given solution.
However, it came out that this fix only works for the first time cert creation. Later renewals would not execute the hook!
I explained in detail there why the present solution does not work.
Finally, I also suggested a very simple fix.
I have also add a comment in github, where the feature was introduced:
It is indeed no big change.
I (and many others for sure) would be thankful if you could apply this fix into the next release.
