I do not get the SYSLOG: ... in the debug log (either with 4.94.2 or
with 4.94.2+taintwarn). Looking at the source I see that it is only emitted
if(f.running_in_test_harness).

The lack of duplicate logging shows up early, the startup message
2021-05-09 11:13:53 exim 4.94.2 daemon started: pid=2321, -q30m, listening for
SMTP on [127.0.0.1]:25 [::1]:25
already only shows up in the mainlog.

I will send you complete debug logs off-bugzilla, in case I miss something I
should have sanitized.
