I understand it as:
* There was a change 7 years ago to add a validator disabling negative values.
- This was regarded a good thing at this time by the author of the change.
- It did not work as intended.
- It was not widely discusses as no change in behaviour was seen.
* For 2.2, the validator was fixed.
- now actual behaviour change was seen
- a majority of developers did not like this change
- it was decided to keep the old behaviour for 2.2.0
This leaves open the possibility to (re)activate the validator in 2.2.1
after a non-rushed discussion.
I still favour allowing values that
* LaTeX allows,
* have use cases (maybe rare) and
* are not "dangerous".
