True, but for that alone I'd assume that there's no lack of trying. Innovation through dozens (hundreds?) of suppliers each trying to sell to installation companies.

In old-google-speak those are certainly not moonshot projects, but I'm sue that this organic innovation of many hands, eyes and minds has already achieved quite a bit. In the other hand that kind of innovation is prone to getting stuck in local optima and one of the reasons I believe that the "scaffolding as robot rails" approach might be worthwhile is that it would be somewhat moonshotty, and that moonshottyness could very well knock the state of the art out of local optima if it happens to be stuck.
