The dark side of submitting in LaTeX

Point 1. On the publishers portals, LaTeX looks old-fashioned. The compilation seemed romantic in the early students years, but currently it looks awful to me: LaTeX -> BibTeX -> LaTeX -> DVI -> PS -> PDF. ShareLaTeX is great, yet to submit a paper one has to return to the old-school compilation.

Point 2. Grammarly does not work with bare TeX even in ShareLaTeX. There is so much space for improvement, where publishers could significantly contribute. Do they?

Point 3. Vector figures are great. Why do publishers ask for eps? The encapsulated postscript is outdated. For instance, it does not support transparency and also gradients, to a certain extent.
