Currently the py[w] command will launch the latest python by default however I feel that this discourages the testing of pre-releases & release candidates as once they are installed they will become the default.

The problem with this is it would either make the Python launcher have to be updated with every release or it would have to download some data to know what versions are not considered stable. Both of these go against the general design of the launcher as it's meant to not require updating, be future-compatible, and extremely fast.
When you start Python, it reports its version. How discoverable is that version for the launcher, and for tools in general?
