Future possibilities


Q: value of bugs (e.g., floats) vs. features?

Q: value of copying what other browsers do (so that authors can use them on the Web) vs. doing the things that we think are most important (and hoping other browsers will follow)?

Q: How much should we improve bad solutions (e.g., floats for layout) vs. come up with better ones (e.g., flexbox, grids)?

Q: Does spec completeness matter? (e.g., CSS2.1: @page, run-in)
