Feature Request: preventing loading / unloading systems about pixijs

[bigtimebuddy]

Here's an example to illustrate it a little clearer: https://jsfiddle.net/bigtimebuddy/enhujtbr/

When you remove() the extension is it removing the Renderer's system from getting installed when the Renderer is created. It does not, however, prevent the installation of the mixins on DisplayObjects. In order to achieve that you need to do something like we discussed here #10392 and not import the code.

Indeed, and I raised 2 issues because extensions and "renderables" are different topics.

As I answered on #10392 short of patching a number of files, extensions always initialize.

Potentially the extensions could "initialize late", and the mixins would also be applied late. It could be automatic when you first create a Pixi Application, or allow explicitly calling an extensions init function if that'd be needed. This would allow removing an extension before it has side effects.
