    I don't know, hence why I'm asking to somebody else to review 😊

    For the record, I found the commit changing the value from 23 dBm to 0 dBm:

        sysmobts: Don't start with 0dBm TRX output power before ramping
        
        In case a system has a high-gain external PA (like a 40dB PA) connected
        externally, we cannot simply switch the transceiver to 0 dBm in
        trx_init() only to then start the ramping at much lower levels once the 
        PHJ completes in trx_init_compl_cb().  The result would be a short
        0 + 40 dBm spike followed by later ramping.  We want to avoid that
        spike, particularly its associated inrush current, so let's bring up the 
        board with smething very conservative like -50 dBm, and then ramp from
        there.
