Well it all makes a lot of sense but you have to understand it first. That takes time. I’m typesetting stuff which has complex mathematics in it so there are no better solutions. This is the best human solution we have.
There are some workflows that you can’t do with anything else as well. For example I am doing a lot of semi hand drawn diagrams on my iPad in Goodnotes. These are exported as vector PDFs and trimmed and included in the LaTeX documents as figures. They are fully vector end to end which is a complete pain in the ass on any other package.
As for hybrid PDFs I don’t know. I am mostly interested in not shopping the source document.
