Maybe the better solution is to have some variable / flag in the softbody data structure to indicate shared caches, rather than relying on ID flags.

This is fairly similar to other shared pointers (such as edit-mesh or eevee light cache data), the depsgraph has logic that handles these so I think it's simplest to handle this the same way.

Although this has some drawbacks too, see: D11228
