Jein.
The one scenario where this really matters (apart from Molos six 85s charging at you) is that ie. an early Sherman can now shut down any and all harassment pretty risk free and has much better opportunities for gaining squadwipes. This has far and away the greatest impact on how the game will play out. Since in the "typical" 1v1, Axis (both OH and OKW) have to come from behind and will have less map and later medium armour, this affects them much more severely than it does the Allies.
I see. That might be a problem indeed. I guess retreat paths have to be mined to prevent squad wipes. AT as support for harassment attempts might be needed.
Harassing will definitely be riskier and harder to execute. I can't say which faction suffers the most from this change. In theory, Axis can just as well wipe harassing units on retreat.
We'll see how it works out.
