Different plugin groups to support different use cases (diverse-defaults for short)

There are many different categories of bevy applications. Each use case has a sufficiently different commonsense default configuration to warrant different use case specific default plugins. This RFC is a proposal to consider making such a change.

Instead of having different PluginGroups, I think this would be better suited for compilation features:

• they reduce compile time
• they guarantee that the code won't be present
• they are the only way to have different const values
• they work well with compilation target, which is what you call "divergent platform"
• they are already present and mostly usable that way in Bevy

For example, for a 2d game that won't use UI but will still display text in the 2d world, I use only those features: "bevy_core_pipeline", "bevy_sprite", "bevy_winit", "bevy_render", "bevy_text", "png".

Features are probably not documented enough and not really friendly, Bevy could add meta features to group them into logical groups like you describe here.

That's a really nice idea @mockersf and I think this solves the problem I am seeking to address in an even nicer way with the additional benefits you outlined!! :) :100:
