In "my" days it was promoted to specify the type of wind shear. If during the APP a "negative" shear or performance decreasing shear, was reported, a drop in speed (IAS) could be expected. The confusing about it that the same (TWR) controller had to report this same shear as a "positive" shear to departing A/C.
In this case the arriving A/C should have been told to expect a "positive" shear.
Is this still needed to/practiced?
