They're headed the way of Dropbox. As Steve Jobs famously said to Dropbox when trying to purchase them: You don't have a product, you have a feature.
For Dropbox it took way longer to get to that point than anyone expected, but Microsoft, Apple, and Google have all copied the Dropbox feature. 1Password is headed in the same direction and Apple is leading the pack in making it redundant. If the password section of Settings in macOS gets a separate app and a way to share passwords, 1P will end up in the same tough spot as Dropbox.
I am eagerly anticipating the release of the Apple Passwords App. However, initially limiting it to Apple devices alone would not be practical for most users who require password sharing capabilities.
This is similar to the case of iMessage vs WhatsApp, where the lack of a Windows/Android App for iMessage renders it unused by my friends and unpopular in regions where Android phones are prevalent.
