🟡 Experimental Python starters always fail
With --experimental, each new framework reaches create without generated files. The experimental path skips copyTemplateFiles, so project setup fails on the missing package.
Learn more
Experimental C3 normally runs a framework generator, skips static template copying, and delegates configuration to wrangler setup. These three configs define only copyFiles, so selecting one in experimental mode creates no directory before package-name processing runs.
Example: create-cloudflare app --experimental --framework django --lang python selects Django from this map. create skips copyTemplateFiles, then updatePackageName tries to read app/package.json instead of producing a Django project.
Recommended fix: Either omit these static frameworks from getFrameworkMap({ experimental: true }), or make the experimental creation path copy static templates before running autoconfiguration.

🟡 Defaults reject Python framework selection
With --accept-defaults, --framework django inherits lang=ts. Language filtering removes every new Python framework, so non-interactive creation reports it unsupported.
Learn more
The --accept-defaults option populates unspecified arguments from C3_DEFAULTS, whose language is ts. createContext filters the framework map by that language before resolving the explicitly requested framework. Since each new config exposes only a python variant, all three disappear from the map.
Example: create-cloudflare app --framework django --accept-defaults --no-deploy fails with Unsupported framework: django. The same command with --lang python succeeds.
Recommended fix: Derive lang="python" when one of these Python-only frameworks is explicitly selected and no language was explicitly supplied. Preserve rejection for an explicitly incompatible --lang value.

🟨 Django starter lacks allowed hosts
The starter uses ALLOWED_HOSTS=[] with DEBUG=False. Django rejects normal Worker hostnames, encouraging unsafe wildcard configuration as a workaround.

Add Python web frameworks starter kits for Django, FastAPI, Flask. Python workers team recently added support for these frameworks, so it would be good to have these templates.
