Which is half of why this is an insoluble problem. There's no solution that doesn't impose some workflow or wetware overhead on introduction.
Installing "Tabs for indentation, spaces for alignment" on wetware is probably the best solution in terms of maximizing utility for minimized development/workflow costs. But even that is going present a wetware tax for some developers, and it's not superior in terms of utility to the article's proposal.
We don't know that there's no solution. One of your siblings suggested having the editor just use space alignment. I can't see any reason why that wouldn't work either and was the idea I had in mind.
But installing ideas onto wetware is perhaps the most expensive thing that can ever be considered. Because it often involves fighting a war.
