I propose SWC enables every feature by default, and accepts an optional browserlist parameter that will control what browsers are the targets. Things like IE > 6
or > 1%
. That can be done in JS easily.

I thought this is almost done, but determining .swcrc
api is quite hard. I want to follow it of babel, but there is a problem.
Invoking browserslist from rust code is not easy. It means that allowing browserslist query to be specified on .swcrc is not a trivial task.
There are some options.
- Invoke browserlist via node executable
It would make swc slow, but the query result can be cached.
- Inject browserslist function while creating a instance of Compiler.
This is hard at the moment. neon-bindings/neon#375 is required.
- Handle browsers query from node
This option requires removing target from .swcrc
I'll go with first option.
