Probably.

Past Porsches have 'killed' some of their 'customers', and since the Audi TT debaucle, Porsche Group and corporate 'sister' Audi and probably other VW division have also added rear spoilers as palliatives for separation-induced rear- lift instability.
* The 1972 911 Carrera RS 2.7 was an 'industry first.'
* The Porsche Panamera has it.
* Audi A7.
* Bugatti Veyron, Chiron
* VW's Bentley division's fastbacks conspicuously do not have rear spoilers, in spite of 190+ mph top speeds.

As the Macan is the top-selling Porsche, and it's the first Porsche ICE-to-BEV conversion, the Pseudo- Jaray roofline creates 'range anxiety' issues because it's aerodynamically 'dirty', compared to 'Taycan', 911 GT1, and the Porsche 918 for instance.
I suppose Michael Mauer allowed the styling to deviate as much as he dared, so as to not scare off buyers.
And Walter de Silva, who watches over all 'Volkswagen AG' design products also signed off, so, VW is just going down a familiar road.

To compete against the benchmarked Tesla CUV, I suspect that the Macan's spoiler will have a 'minimum-drag' setting to protect battery range, and a 'safety' ( 'direct-downforce' ) setting, to keep customers alive on the few remaining unlimited-speed portions of the Autobahn/ Autostrada.
Porsche is targeting the Macan EV to be the 'highest-performance' CUV in it's market segment. If it's range 'stinks', their hoping that 'fast-charging' will swing consumers.
