Is there any documentation of supported tags that we could link to?

In theory, this works for any set UserTag, so this is something that could be exposed as a CLI option at some point so users can cache samples associated with any UserTag defined in their code. However, I think it's best to just start with this single case so we can make progress on tooling for profiling application startup times.

Oh, I see, so UserTags are defined in user code?

Yup, but we're setting this particular tag in the engine and resetting to default in the framework after everything's initialized. See UserTag.
