Content that is mesh based, so hair, wearables and props, all start with a mesh, made in whatever modeller. From there the decision to make it a store product is a commercial one. How much time will it take and how much nett revenue will it bring?

What is missing is means to speed up or circumvent the steps that take the most working time to come from mesh to product in the store. Both investment and nett revenue are stochastic variables so one looks at expectations.

Expected revenue is always a guess, driven by factors outside the control of the vendor. If your launch campaign is drowned into someone else's, you know better for next time. This is commercial life, of course, but a parameter that becomes very important on the small scale most people work on. Stores could work on reducing uncertainty of individual income through grouping of products.

Expected work is much affected by perception of reliability of the tools. If creators can rely on 'copy joint setup from...' to provide a proper result they are more likely to take the plunge than when they know they will have to spend hours and hours to brush away the ripples left by the process.

Would creators have a tool that in an overnight process can reliably optimize vertex weights to match animation bending with results from dynamic simulations and get the errors as a JCM, that would drastically reduce the time they need to spend on rigging. Cost wouldn't be hours of work but an odd kWh of electrictric power.
