This technique looks good. I like how it's consistent with previous use of ConfigManager.
There is the question, that you asked internally, of whether already-started traces should be allowed to be sent. A design where the answer is "no" might be better from a user perspective, but the implementation would be less elegant.
Please fix the test failure showing in CI, and also please add tests for the new behavior.

We could follow the lead of TracerConfig and omit the get_ prefix. It's fine either way.
Yes, please do add a comment here. Maybe:
// Return whether spans should be sent to the collector.
I don't like the use of the word "should." Something like that, anyway.
