Thank you for sharing your perspective – it’s great to hear your story and how Android’s freedom has helped you to create a setup that works for you. The good news is that while we’re changing the standard way that icons are created, we’re not taking away any of the creative freedom that the platform offers. That is you can still download and use different launchers and they are free to do whatever they like such as use icon packs with unique shaped icons.
There’s always a fine line when designing a platform; optimizing for most users while still enabling unique use cases. I hope that you’re still able to create a setup that works for you after these changes land.
