Could you elaborate? I've been using it for a decade, for all my projects big and small, and it's been a _massive_ time saver compared to any of the alternatives. It's fast, well documented, and it doesn't rebuild/retest stuff when it doesn't have to. I've also done multiplatform builds with it, as well as cross-builds to ARM. Not once did I have the need for any "upkeep". At Google there was a team to do that, of course, but even outside Google, even very early on when Bazel was just released, the maintenance is pretty minimal, and the build files are by far the most readable of any build system I have used so far in 20+ years in this industry.
