This does seem like it will degrade future bug reports, and prevent user made fixes from sanity checking their own modeling.
I look at things like this in the stock DCS weapons modeling: https://gfycat.com/genuinerealisticblacklab
Where a 2,000lb bomb with 900-1000lb of explosive material only destroys the object it directly impacts and its just to obviously wrong (it didn't even scratch the AA truck 6 feet away across the street!). If its going to be made even harder for users/servers to generate their own fixes around this poor modeling then it absolutely needs to be fixed in base game DCS, for the sake of everyone. The data on MK-XX bomb series is very publicly available (hell it was linked above) and provides the base warhead for like 50%+ of the A/G weapons in game, that would be a good place to start.
