There are a few reasons for making this test only: * The code is only used by tests and utilities. * The pure interface has only a single implementation so an interface isn't really needed. (a followup change could remove it altogether) * The implementation always incorporates locking regardless of how the class gets used. See e.g. previous use in the Packet class. * The implementation is a layer on top of RtpUtility::RtpHeaderParser which is sufficient for most production cases.
