because

1. ES modules support has increased to all major evergreen browsers.

2. Esbuild has come out which shows faster results than tools (babel, typescript)

3. Improving current ones means supporting hacks and incorrect code patterns, which is not wanted.

The above factors has resulted in multiple build tools with vite being one of them

None of these are my concern as a developer. I just want a tool that works. I'd rather take som duct tape and 5 new features I __really want__ than a fancy new tool that'll be the same mess 5 years later and has less features.
