I thought linus had lost it for a second there, until I saw it's just named after him and not something he created. I generally disagree - I think that having many developers with a shallow understanding of the whole codebase scales less-than-linearly with the number of devs.

It's probably less actively harmful than new product development, but I'd still say a team of 50 is probably larger than is necessary for the amount of usage flutter gets.
