--import-mode=importlib <import-mode-importlib> now tries to import modules using the standard import mechanism (but still without changing :pysys.path), falling back to importing modules directly only if that fails.
This means that installed packages will be imported under their canonical name if possible first, for example app.core.models, instead of having the module name always be derived from their path (for example .env310.lib.site_packages.app.core.models).
