All the other content is still there, people who avoided Coil or can't get into a static and don't like PFing still won't go into Coil, if you're already doing Coil you can beat it in less than an hour or two and potentially get sands and oils faster than running around maps. If you're already doing Coil you either already have all the best things from there or if you're unlucky and haven't gotten anything in weeks then Hunts can complement your weekly Coil loot. People are still doing ST, other dungeons, primals, Frontlines and what not, I really see no issue. In 3 months none of this gear will be relevant anymore anyway, if anything all this just shows the flaws of vertical progression, relying too much on instanced content and the best gear being found only in dungeons.
