Support for a metadata callback has been added with the latest commit

Simple answer is yes. And it's already implemented in this library.
Here

ESP32-A2DP/src/BluetoothA2DPSink.cpp

Line 397 in 9ceec8e

esp_avrc_ct_send_metadata_cmd(0, ESP_AVRC_MD_ATTR_TITLE | ESP_AVRC_MD_ATTR_ARTIST | ESP_AVRC_MD_ATTR_ALBUM | ESP_AVRC_MD_ATTR_GENRE);
you're telling what you want to get.
And here

ESP32-A2DP/src/BluetoothA2DPSink.cpp

Line 434 in 9ceec8e

case ESP_AVRC_CT_METADATA_RSP_EVT: {
you're getting that.
More information about that can be read in ESP32 documentation (https://docs.espressif.com/projects/esp-idf/en/v3.3/api-reference/bluetooth/esp_avrc.html).

Thank you so much for your answer! I went trough the code and it seems that everything I asked is indeed possible. Now I have to find the time and courage to go deeper in the code to understand how it works, it'a maybe a bit over my skills!
Cheers.

I think it would be cool to have some callbacks to make it easy to use.

Yes, it should. But I would also like a callback for connection state changes, so I could notify the user about this, e.g. let a LED blink or so ..
