Honestly executives and board members who receive performance bonuses and golden parachutes should carry extra liability, such that these perks can be denied or even clawed back (and used to help the damages) when their decisions have these sort of outcomes. Nothing wrong with making more when things go well, but if you’re going to take a larger piece of the pie, then you need to be prepared to take a smaller piece when things go wrong (aka, cut executive pay before layoffs, etc.).
The concern for code duplication is valid, but as the article mentioned it is also a while off until the Nova project is mainlined. I honestly never thought of how the work to bring in Rust to mainline may in effect lead to a more complete deprecation of older hardware as we start to change API’s older/unmaintained components aren’t updated. On the flip side, trimming out older stuff might save maintainer work going forward.
