googleapiclient downloads the discovery docs for a Google API service at runtime and then constructs a client. Issue #1063 captures the need to move to a static package where the discovery docs are not fetched at run time. An incremental step towards satisfying #1063 would be to create a folder with static Google API discovery documents in this repo. The discoveries folder in the googleapis/discovery-artifact-manager repo has an up to date copy of the discovery documents. One approach would be to modify synth.py to copy the discovery documents from discovery-artifact-manager similar to how it is done here.
