There was a problem hiding this comment.
The fact that this specific string is a substring of sys.version seems like an implementation detail. The docs even discourage extracting information out of sys.version.
A quick chatgpt tells me that sysconfig.get_config_var("Py_GIL_DISABLED") is an equivalent way to check for this, though we need to test it out.
UPDATE: On my Ubuntu 25.04 with python 3.13 this config var check is accurate.
