Comment:
I don't know any reason to prefer the non-legacy build other than avoid polyfills ([relevant FAQ section](https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#which-browsersenvironments-are-supported)), maybe we could ask upstream? Also, https://github.com/mozilla/pdf.js/issues/14343#issuecomment-986064030 states there aren't any plans to remove the legacy build.
