Hello @egorikftp I want to pick this up, but looking at compose icons and I can see it consolidates a few icon packs. I'd like to suggest we prioritize direct implementations for popular icon providers rather than relying solely on Compose Icons as an intermediary.
Going direct allows us have:

• Provider-Specific Features like we have for Material Symbols(Variable fonts fill, weight, Outlined/Rounded/Sharp etc)
  These features would be lost or limited through Compose Icons abstraction.
• one less abstraction layer
• No dependency on third-party update cycles
• only fetch icons when browsing that provider
• direct access to latest icons/features

Think we can do:
1: Direct Implementations

• Material Symbols 3,476 icons - Already implemented
• Lucide 1,520 icons
• Heroicons 324 icons
• Bootstrap Icons 1,355 icons
  ...

2: Compose Icons Integration
As a "More Icon Packs" option for less-common providers
VSCode codicon, Radix Icons, etc.

Let me know what you think

@t-regbs Hello, I agree that a direct implementation can bring us more benefits 🙂
I will update the epic with the actual icon providers
