I would chime in here and remind the crowd that I never suggested that “Cycles/Eevee/etc could not do the same thing better.” It unquestionably can. But, the BI renderer is still perfectly legitimate, and there are still a helluva lot of Blender projects which were painstakingly built – and then, sold – which use it. Although it is no longer “the state of the art” given the enormous advantages in (especially) GPU technology which have occurred over the years, that also is not the point. “Ever since the NaN days,” BI was there, and I argue that there is still a business need to continue to have access to it … alongside other alternatives.
And also, if I may say (subjectively) … “it is still a damn good engine,” and different from all the others. It’s still an asset to the Blender system. No, it doesn’t work like the others do, but it sure-as-hell works!
I’m perfectly happy that “its role and its positioning within the product may change.” Time marches on. But, don’t remove the technical capability to fire-up “Blender latest,” select this render-engine, and soon produce exactly the same image that “Blender” could produce in all of its past. If you still need it, or if you still simply want it, you should have it at your fingertips.
Now that the development team has accomplished the very-messy work of excising it from the core of the product, now they can – if they will – repackage it and bring it back, better than ever it was before.
