> The metric name consists of various components (like job ID, task ID), that are then joined by a delimiter(commonly {{.}}).
> The delimiter isn't just for convention, but also carries semantics for many metric backends, as they organize metrics based on the delimiter.
> This can behave in unfortunate ways if the delimiter is contained with a given component, as it will now be split up by the backend.
> We should automatically filter such occurrences to prevent this from happening.
