I'm way late to seeing this, but...what prompted this change?

The `message` parameter is validated in managed code:
https://github.com/mono/mono/blob/master/mcs/class/Mono.Posix/Mono.Unix.Native/Syscall.cs#L3200
https://github.com/mono/mono/blob/master/mcs/class/Mono.Posix/Mono.Unix/UnixMarshal.cs#L366

This change means that '%m' isn't useful in format strings to Syscall.syslog(), as it'll be escaped instead of "passed through" unchanged.
