I'll add that some build systems may have a non-trivial startup cost (for example conda-build sets up an isolated environment with well-defined binaries in it), therefore issuing several CLI commands can be significantly more costly (and/or difficult to optimize for) than issuing several API calls from the same single process invocation.
