T_* rules in snapshots

[Yet Another Ninja]

I was assuming that rules named T_* would be in "testing" mode and would 
not be plublished in daily snapshots.

After installing a snapshot I see stuff like
,T_RCVD_IN_SEMBLACK,T_SURBL_MULTI1,T_SURBL_MULTI2,T_URIBL_BLACK_OVERLAP,T_URIBL_SEM,T_URIBL_SEM_RED,
scoring.
Is this a bork?

Snapshots on
http://svn-master.apache.org/snapshots/spamassassin/
include "rules" and "rulesrc" directories

Shouldn't these be left out and rules only be added via sa-update?
