The problem with inkscape is that, any slight changes to the figures would make the user go deep into the workflow pipeline to make the changes. However using LaTeX packages like TikZ or PSTicks would simplify the workflow and make the document more maintainable.

I think this is one of those things that depend on your actual workflow, content etc. I see your point; for me this hasn't been a problem.
