Dot notation increases opportunities for environment factor mismatches and makes them harder to spot #3877
Description
Issue
This is likely a dup of #3219 , but the advent of Python versions using dot notation affords more opportunities for silent errors. A minimal example is provided below, but the crux of the issue comes down to this: If py310 is handled by the [testenv] environment, and a factor py310-lint is handled by the [testenv:py310-lint] environment, running tox -e py3.10-lint will run the [testenv] environment without warning or complaint, even though py3.10-lint does not appear in tox list.
This fees like a bit like a foot gun, since spotting the difference without warnings or errors is difficult.
This could also be characterized as a feature request: Allow option for short-circuit exit with error if Tox is asked to run on an environment that does not appear in tox list.
Minimal example
