TL;DR: Please focus on gradually reducing the number of dependencies going forward.

I was looking at using the @google-cloud/pubsub module and wanted to dive deeper into how auth worked and ended up in @google-cloud/common. It turns out that @google-cloud/common alone downloads about 39 MiB (~5MB) of files. Awesome! 👍

I don't have any solid recommendations for reducing the number of dependencies but just wanted to bring this up as something to think about going forward.

For instance, did you know that @google-cloud/common indirectly depends on three separate versions of request?

$ find ./node_modules -name request
./node_modules/google-auth-library/node_modules/request
./node_modules/grpc/node_modules/node-pre-gyp/node_modules/request
./node_modules/request

$ cat ./node_modules/google-auth-library/node_modules/request/package.json | jq .version
"2.60.0"

$ cat ./node_modules/grpc/node_modules/node-pre-gyp/node_modules/request/package.json | jq .version
"2.72.0"

$ cat ./node_modules/request/package.json | jq .version
"2.74.0"

Take a look at this awesome dependency visualization of @google-cloud/common if you have a minute.
