Currently, the sourceMap option must be explicitly defined when it'd be much more convenient for it to rely on the value of Webpack's devtool option.

Yeah, this is an unfortunate side-effect - if one sets devtool in the base Webpack config, UglifyJsPlugin should read that config and respond accordingly..

Or at least emit some sort of warning - currently there is no way to tell from build output that sourceMap is needed. If you have 10+ plugins, how do you know which one is causing the issue?

It is actually, IMO, a bug that souceMap: true doesn't get set by UglifyJsPlugin because it alters the way the base Webpack configuration affects the build process.

It was fixed in next major release, because it is breaking change
