What people truly need is a happy medium. Because of the worries of bad reviews and backlash from the community, it's become an all or nothing situation when it comes to mobile platform releases. This is the problem with most software developers. As with the other mobile apps, the ONLY supported file system that it requires are the actual InDesign files and the ability to use images and pdf's in editing. The other is the support of hierarchical file systems.

Just the names and as chosen by the user they become available within the projects. You do not need to preinstall any actual font files. I know that adobe has enough cloud space to add a code snippet directing the app to take the specified font in the app as people use it and giving it a font face attribute, linking the font to the app. As with html5 coding you have open font and font face tags referring them to a css file telling them where to find the font online to sho it. There is a very simple solution for this.

You mention one of the hurdles being unsupported fonts. We do not even need a fully functional version with all of the bells and whistles, but a touch optimized workspace ( as you already have available within the pc software) to be able to edit files sent to us on the fly. I need software that I can load onto my iPad Pro. Taking a computer onto these job sites is not a feasible option. I live on planes traveling the country from job site to job site. I work for a large national GC as a project manager and am also a manufacturer/ distributor of my own product. The real issue comes with people with professions like me. The real issue isn't whether or not a ps or Mac are noting.
