compiling subdependencies down the same way as uppy itself?

[mokutsu-coursera]

Initial checklist

• I understand this is a feature request and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

I noticed when I use @uppy/transloadit, the subdependencies p-retry and component-emitter are not compiled down, causing some compatibility issues due to nullish coalescing and optional chaining in environments where es5 is expected.

Solution

I saw that uppy itself is compiled down here https://github.com/transloadit/uppy/blob/main/babel.config.js, would it make sense for required dependencies to also targeted and compiled?

Alternatives

We're able to workaround this by targeting these 2 subdependencies for compilation in our own build scripts, but it would be nice not to have to do this.
