It seems very difficult for agents to migrate from v2 to v3

I'm not sure..... However, when AI Agent migrating the example, I found that many components were missing and implemented using native tags directly, which resulted in the style becoming ugly

For instance, the following elements are currently missing or unsupported:

• Functions related to buttonStyles are missing.
• The Snippet component is missing.
• Component props hooks related to useSwitch are missing.
• Input no longer supports startContent.
• Navbar-related components are missing.

There may be even more issues; these are just the gaps identified within the example project. I am concerned about this, as it seems migrating from v2 to v3 will be quite difficult.
