"not much work" is absolutely not the feeling I have about it based on some conference talks about the topic (e.g. the various xcode talks, or the Wix talks on intelliJ), and my own thought experiments on getting it tied into Visual Studio / Visual Studio for Mac. I think the Bazel team introduced Aspects and punted the rest for a later date. Now they hope each language/IDE community will take that infrastructure and build out the rest of the ecosystem. I think its too important of a piece of the puzzle to leave to the community.
