There are older articles (https://phaser.io/phaser3/devlog/48) that make mention of Phaser 3 being able to use compressed textures such as PVRTC, S3TC and ETC1.
Looking at the current state of Phaser 3, it would appear that this is no longer supported. Am I correct in assuming that once the Pixi.js renderer was replaced with the new custom WebGL renderer that this functionality got lost along the way?
Currently I see in the source of the renderer that the supported texture extensions are queried but never used (https://github.com/photonstorm/phaser/blob/v3.24.1/src/renderer/webgl/WebGLRenderer.js#L673)
Has anyone else had any experience with getting these compressed texture extensions back up and running within Phaser 3?
