Since Node 12 it has built-in source map support. For cloud run deployments we can start the node server with the flag --enable-source-maps, but for cloud functions we don't have this control.

I don't understand why we still need to install and register the source-map-support NPM package in our code to get source maps to work.

I suggest to have a configuration option that enables the flag, preventing us from having to manually install a package that is considered obsolete for newer versions of Node.
