Hi,
Currently, I have no plan to address this issue.
The commit in question, was not intended for any previous Linux versions.
It was created as part of my handle_tx_event() rework series. Future changes
in said series could potentially trigger the issue, so preemptively preventing
it was both simpler and more secure.
Thanks,
Niklas
