In order to get back to the main topic and also to weigh in to the discussion with more numbers:
While I haven't been able to generate any statistically meaningful in-game data yet (obviously), I've run some theoretical simulations to estimate how the incoming changes to the AOE profiles impact the anti infantry performance of the affected heavy tanks (details on the methodology can be found here
The comparison is based on the number of shots (S2K) and required time (T2K) to kill a full-health, 6-man squad in either "wide", "stacked" or "clumped" formation (Fig 1) at ranges 5, 20 and 40 m.
Fig 1: Formations used in the simulation, numbers below each image indicate average (AV), minimum (Min) and maximum (Max) distance between entities
The resulting average numbers for S2K (Fig 2) and T2K (Fig 3) over 5,000 iterations for the live and WBP-versions of the Tiger, IS-2 and Pershing, as well as the King Tiger and KV-2 for reference can be seen below.

Expectedly, the S2K or T2K values show significant dependence on the squad spacing and range. However, and more important for the actual discussion, you can clearly see that the effect of the AOE changes on the overall anti-inf performance of the Tiger (as well as IS-2 and M26) is rather limited, and the tanks will be nowhere near as "neutered" by these changes as people suggest.
The actual magnitude (see Table 1) is in the range of only 5-10%, and both Pershing and IS-2 seem to be impacted more by the WBP than the Tiger, in particular for more "clumped-up" formations.
