One problem with these sorts of tools is that they encourage people to split their arguments into lots of little pieces, which means arguments for C often end up being A->B, B'->C where B and B' look alike but on closer inspection turn out to be different.

I think that is in fact the point -- so we can see where the argument falls down.

Why is this a problem?

The reason this (splitting the argument into many small pieces) is a problem is that sometimes, checking an argument by going over it with a microscope isn't sufficient.

If the checker is mostly reliable but fallible, a long-enough inferential chain can defeat any specific amount of reliability, making the checker useless at best and maybe even deceptive.

However, even though it is a flaw, it's not a fatal flaw. We can strongly prefer smaller arguments, and maybe there are other techniques too (representing is-a-refinement-of explicitly?).

Sure. But it doesn't seem preferable to just not go over arguments piece by piece.

Promoting "closer inspection" of argument pieces sounds like a win to me, so I'm not sure how this is a problem. Can you elaborate, or perhaps illustrate with an example you've come across?
