Sure, that's the advantage of having a single implementation. The disadvantage is what we're experiencing right now: once that implementation is no longer maintained you're left with no alternative.
That's true. My point was that even with Flash announcing several years ago that it would be sunset, nobody stepped up to build tools that worked with the open technologies of CSS, SVG and JS.
Instead, what we have is a situation where pretty much only corporations with designers and devs on staff (Stripe and Spotify being the major examples) are building the types of sites that used to be doable by a single person using Flash.
