Future of Journalbeat

Journalbeat is currently still marked as experimental/"this might disappear at some point". Is Journalbeat planned to be marked stable/official any time soon?

I am currently at a point where i have to choose between using Journalbeat or using rsyslog->tcp localhost->filebeat w/ syslog input to get event severity and facility, and i would like to know which solution is more future-proof.

Thanks in advance.
