Problem

The elements stats API allows ?include=a&include=b as a way to pass multiple includes kea's URL fangling doesn't support that type of URL

~~let's lean into that and change the API so that it supports both ?include=a&include=b for older clients and include=["a", "b"] for newer clients~~

changes the default for the API to include rageclicks and autocapture since that's what toolbar wants and nothing else uses this API

much simpler that way since we don't need any query params

Analysis of the Pull Request

Overview

The pull request consists of two main changes aimed at improving the PostHog frontend, specifically within the Lemon UI component library:

1. Fixing Tab Bar Animation (PR #21287): This change addresses a UI issue where the tab underline transition in the Lemon UI's tab component was not functioning smoothly. The fix ensures a smoother visual transition when switching between tabs, enhancing the user experience.

2. Cleanup of Unused Feature Flags (PR #21286): This change involves removing unused feature flags from the codebase. Cleaning up these flags can reduce code complexity and potentially improve performance by eliminating unnecessary checks and logic associated with these flags.

Code Quality Assessment

1. Clarity and Readability: The changes made in PR #21287 are clear and easy to understand. The modifications to the SCSS file for the LemonTabs component are well-documented with comments, making it easy to grasp the purpose of each style rule. The use of CSS custom properties (variables) like --lemon-tabs-slider-width and --lemon-tabs-slider-offset enhances readability and maintainability.

2. Best Practices: The use of CSS transitions to achieve smooth animations is a standard practice in modern web development. Adjusting the duration and easing function of the transitions demonstrates attention to detail in creating a pleasant user interface.

3. Performance Considerations: The cleanup of unused feature flags (PR #21286) is a positive step towards improving codebase health and potentially enhancing performance. Removing dead code reduces the overall size of the codebase, making it faster for developers to navigate and maintain. Although the direct impact on runtime performance might be minimal, simplifying feature flag logic can lead to more predictable code execution paths.
