First of all it was intentional change, not temporary implementation. Back in early pre-release interview with Rock Paper Shotgun Larian’s system designer used reaction as an example of a system they are changing as literal adaptation “wouldn’t feel good in a computer game”.
As others have mentioned it’s been confirmed by Larian that they are working on changes to the reactions but how extensive those changes might be is anyones guess. Hopefully we will get to see them in the next patch.
