State of TCPStats analyzer?

Does anybody remember what the state of the TCPStats analyzer is?

We have this in scripts/base/frameworks/analyzer/main.bro:

        ## A set of analyzers to disable by default at startup. The default set
        ## contains legacy analyzers that are no longer supported.
        global disabled_analyzers: set[Analyzer::Tag] = {
        } &redef;

I understand why the first three are in there, but I don't recall
anything about TCPSTATS.
