Design question - why was acorn-jsx chosen instead the standard acorn parser

[shanemcandrewai]

Hello,

I tried transpiling the Ace editor tree to ES6 but it failed due to several problems such as missing file extensions (.js) on the import module-names and Error: Dynamic module names are not supported, so I had to dig into the code which leads to my question - why was acorn-jsx chosen instead the standard acorn parser?
