Great workaround! For my case (using Linux Mint 19.1, based on Ubuntu), I had to add some extra steps:
a. changing line 1 of the script #!/bin/sh to #!/bin/bash (as sh in Mint/Ubuntu is a very basic shell interpreter, unable to follow your script)
b. creating a systemd service pointing to your script named "auto-enable-a2dp.service" (see: https://www.pcsuggest.com/run-shell-scripts-from-udev-rules/)
c. changing line 3 of the rule, replacing RUN with TAG+="systemd", ENV{SYSTEMD_WANTS}="auto-enable-a2dp.service"
d. installing a last dependency 'sudo apt install systemd-container'
It is still possible to debug the service by tapping 'systemctl status auto-enable-a2dp.service'
Worked for me. Thanks :)

It Works well on Manjaro KDE.
I don't know what I am missing but I can get this to work on Manjaro. My headphones always default to SBC even if I have needed ldac modules etc installed.
