samsung-laptop module in UEFI

Hi everyone, I'm new here and after searching the internet I found no good answer to this.

I know that the samsung-laptop module is automatically blacklisted when a linux installation is done in UEFI mode. This was a measure to prevent the samsung bricking that cursed this laptops in the past.
But since then the firmware was already fixed.
I also read that this module still has some other bugs in UEFI mode and this is one of the main reasons that it is still blacklisted.
Since some functions depend on this module to work, I would like to know if there is any plans to fix it and remove the blacklisting of this module.

I don't know if this is the appropriate place to ask this, if not just redirect me...

How do you know this?
Is it related to this 2012 bug report?

There is no "samsung-laptop" module blacklisted in my Debian sid EFI-mode installation...

If you wish to remove blacklisting for any module, examine the contents of /etc/modprobe.d/ and remove (or comment out) any line stating `blacklist samsung-laptop`

I read in several forums and tested against some live usbs, if I boot in csm everything works but UEFI the wireless key toggle and keyboard backlight don't work.

One recent place that this blacklisting is acknowledged is here:
where you can read:
This mode is also needed in UEFI, but there samsung-laptop is
unfortunately disabled.
or here

or even here
from this bug report
