Hi @offbyone, this is a valid concern, thank you for reporting it!
The latest action release v1.0.6 adds a set of optional inputs that allow to lock tracing library versions.
The installer script at https://install.datadoghq.com/scripts/install_test_visibility_v1.sh does not make any versioning guarantees; it performs unversioned installations of the libraries from the respective packaging systems.
