Made the test, and it's a big NOPE !
Starting manually an agetty with the 57600 option does no good, still
stuck with 9600bps.
So it's on for the agetty bug.

Title:
console port speed impossible to set on ttyUSB0
Status in util-linux package in Ubuntu:
New
Bug description:
I want to add a console port on a Ubuntu machine to be able to access
it from a terminal server.
This machine has no serial port but lots of USB ports (like most nowadays).
I use a USB-to-serial adapter to have the ttyUSB0 up and listening.
I copied /lib/systemd/system/serial-getty at .service to
/lib/systemd/system/serial-getty at ttyUSB0.service and set the speed to
57600
+++++++++++
[Service]
ExecStart=-/sbin/agetty --keep-baud 57600 %I $TERM
+++++++++++
the service status shows the right speed
+++++++++++
$ sudo systemctl status serial-getty at ttyUSB0.service
● serial-getty at ttyUSB0.service - Serial Getty on ttyUSB0

Even so, I can't log in from the serial port at a speed other than
9600...
With such settings I shouldn't even be able to get a right answer at
9600bps, only garbage.
