It's not clear to me that the intent of that dependency project is to 
concatenate proofs.  Is that what you guys think it's purpose is?  It seems, to 
me, more like a reliability analysis, where the trustworthiness of any 
component depends (to a greater or lesser) extent on the trustworthiness of its 
parts ... weakest link of the (inferential) chain and all that.  I've seen the 
misapplication of various numerical solutions throughout my career.  And one of 
the important aspects of applying any given algorithm is the assurance that its 
inputs satisfy whatever requirements/assumptions are necessary for the output 
to be trustworthy.  This seems similar.

Of course not.  Not to mention that there are often several different proofs of 
any significant theorem.

I can see that the proof of a theorem can be constructed by concatenating 
proofs of theorems that it depends on but I wonder if that would produce the 
most succinct and comprehensible proof.

    > TheoremDep contains many theorems and shows you the dependencies
    for each theorem. Theorem X is said to be dependent on theorem Y
    iff Y is used as a lemma in the proof of X. Therefore, this
    website presents proofs in a way which simultaneously achieves the
    goals of not assuming any prior knowledge and making it easy to
    skip parts you already know.
