I find it hard to imagine that wounds in this genus would not close as
in other trees,

Yet it's true. I can show you on my own Juniper bonsai. No, the fact that
it is a bonsai has nothing to do with it. Other pruned bonsai heal just like
outdoor trees.

I am not one to argue with the facts, but could you provide a little more
detail? Are those wounds never overgrown or only at a very late stage? If
these are never overgrown then a big trunk of Juniperus should be full of
holes where the branches used to be?
