Finally word from Google that SMIL SVG animation will not be removed without a suitable replacement!
Philip Rogers, Senior Software Engineer, Google.
In the 15 months since we announced our intention to deprecate and eventually remove SMIL, we’ve heard a variety of opinions from members of the community. We value all of your feedback, and it's clear that there are use cases serviced by SMIL that just don’t have high-fidelity replacements yet. As a result, we’ve decided to suspend our intent to deprecate and take smaller steps toward other options.
We firmly believe that SMIL is not in the best long-term interests of the open web platform for several reasons:
-There is no clear path towards broad cross-browser support.
-The vendors which support SMIL have implementations that continue to vary widely, even after more than a decade of support.
-There are high-quality cross-platform replacement features on the horizon.
However, your feedback has made it clear that removing SMIL today would be taking away a feature that our community relies on. For example, the most common use case of SMIL is to animate SVG content inside image tags. While in theory CSS animations can animate this content, there are still missing features and bugs on all platforms that make SMIL a better option for now. For example, motion-path, path morphing, and the subset of SVG properties for which animation is supported all vary between platforms and browsers.
Given these gaps in support, we'll instead proceed over the next few months by:
-Proposing removal of pieces of SMIL that don’t enjoy widespread use.
-Improving our own CSS animations implementation.
-Filing bugs with browser vendors to help solidify their CSS animations implementations.
-Continuing to support and promote modern alternatives like motion-path and SVG 2.
Additionally, before we pursue deprecation of SMIL further, we'll make sure there's are automatic polyfill- and server-based solutions for any content that relies on it.
It’s the Chromium community that make this an awesome project to work on. Thanks to everyone for your feedback and we look forward to hearing from you into the future!
