This is the version in Bullseye (and Bookworm and Sid):
$ esptool version
esptool.py v2.8
2.8
It does not correctly identify e.g. the ESP32-PICO-V3-02, as found on
the Adafruit ESP32 Feather V2, and it can not write the flash:
$ esptool --port /dev/ttyACM2 chip_id
esptool.py v2.8
Serial port /dev/ttyACM2

Chip is unknown ESP32 (revision 3)

The latest version (installed with pip) is 4.4:
$ ~/.local/bin/esptool.py version
esptool.py v4.4
4.4
It works fine with this newer module, and it can write the flash:
$ ~/.local/bin/esptool.py --port /dev/ttyACM2 chip_id
esptool.py v4.4

An updated package would be appreciated. Thanks!
