The hardest part is getting any traction with it.

Developers have no incentive to go the extra mile to publish on your store, because there are no users and it is extra work.

Users have no incentive to install your store, because there is barely anything on it.

OEMs have no incentive to preinstall your store, because you don't have any content (which devalues their product) and they don't gain anything from it. If they are willing to roll their own store, they at least rake in all the profit from it.
