That's because merging two things is inherently complex. You need a complete understanding of both how they work and all the things they interact with. That's why everyone hates merging. You're welcome to take a crack at it, however you're looking at hundreds of hours of work to reverse-engineer all the formats that Adobe and Autodesk use plus whatever new tools are on the horizon that you don't know about yet. AFAIK there isn't a single tool out there that can render a PSD to PNG reliably(aside from scripted photoshop) so thinking we would be able to cover the entire suite of tools is a bit naive.
