This standard binding capability has made Ada much less objectionable to people with large legacy systems. It does take time to learn to use the tools. The Ada tools are expensive because the market is smaller. Part of my job is to increase the commercial market to reduce the price points. If the market gets bigger by commercializing Ada thereby increasing demand, there will be more venture capital and the price points should come down.
Cost is a problem.
I don't think the prices on the new TAC IV contract would encourage anyone to develop in Ada. Some things are looking more promising. By November, Ada compilers should be available in local computer stores, but we don't know for how much. By January or February of next year, it will be out. It takes longer to program in Ada than it does in other languages.
