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.
