I am finding the following guidance confusing:
The svg version replaces the need for a 1x, 1.5x, and 2x version, but should follow the same nominal size guidelines, fitting within 135px wide and 155px tall when resized to 135px wide. The key will be deprecated in future and its use is not recommended.
SVG can fulfil the need of three other keys, so do users need to use the three other keys, or do they need to prepare for SVG being deprecated? (It is hard to believe the SVG is being deprecated given this.)
