Description

How are you using Babel?
@babel/cli
Input code
// ...any code here...
Configuration file name
babel.config.js
Configuration
Any one of these:
module.exports = {
sourceMaps: true, // <---------------------------------------- nothing happens
plugins: [
['@babel/plugin-proposal-optional-chaining', {}],
['@babel/plugin-proposal-nullish-coalescing-operator', {}],
['@babel/plugin-transform-typescript', {allowDeclareFields: true}],
['@babel/plugin-proposal-decorators', {version: '2022-03'}],
['@babel/plugin-proposal-class-static-block'],
],
presets: [
['@babel/preset-typescript', {isTSX: true, allExtensions: true, onlyRemoveTypeImports: true}],
['babel-preset-solid', {moduleName: '@lume/element'}],
],
}module.exports = {
sourceMaps: 'inline', // <---------------------------------------- nothing happens
plugins: [
['@babel/plugin-proposal-optional-chaining', {}],
['@babel/plugin-proposal-nullish-coalescing-operator', {}],
['@babel/plugin-transform-typescript', {allowDeclareFields: true}],
['@babel/plugin-proposal-decorators', {version: '2022-03'}],
['@babel/plugin-proposal-class-static-block'],
],
presets: [
['@babel/preset-typescript', {isTSX: true, allExtensions: true, onlyRemoveTypeImports: true}],
['babel-preset-solid', {moduleName: '@lume/element'}],
],
}Current and expected behavior
Expected: Source maps are outputted.
The 'both' option does output source maps, but only inline (?), and there is apparently no way to make it output separate files.
Environment

OS: macOS 12.5
Binaries:
Node: 18.8.0 - ~/.n-node-versions/bin/node
npm: 8.19.1 - ~/.npm-packages/bin/npm
npmPackages:

babel-loader: ^8.2.2 => 8.2.5
babel-preset-solid: ^1.0.0 => 1.5.4
webpack: ^5.72.0 => 5.74.0
Possible solution
Make sourceMaps: true do something rather than being a useless option that leads people to false expectations, or remove the option.
Also make it possible to output separate files.
