Companies making different length rear triangles is interesting. I kind of hope they start offering customers the opportunity to mix and match front and rear triangles since as you note what is the "best" CS length \[or ratio to FC\] is not a settled issue. It would be great to be able to order up you CS length and FC to meet your needs. Even if there was an up charge for the service to cover the extra costs or if it was offered as a frame only option to avoid the hassles of adjusting complete bikes.
Companies that are offering adjustable CS are slicing the problem another way since they can cover the desired CS length range with fewer rear triangles. It's also nice as a customer to be able to change CS length as you may want your bike shorter on slow techy days and longer on high speed days. Adjustable CS combined with adjustable FC \[ie Guerrilla Gravity\] gives the customer a lot of ways to tweak their bikes.
The other obvious option is made to order bikes like what the Athertons are offering. Where a customer can just dial in their preferred CS/FC STA/HTA...at least within a certain range. As 3-D printing for consumer goods becomes more common the prices for these items can drop making custom or semi-custom bikes affordable for a wider audience.
