Thank you for your answer !
I hope it will become a thing but I'll work with it :)

I know we're REALLY close to EA, but seconding this! It doesn't have to be a huge amount, but having more than just weapon, head, body, arm, leg, accessory would be nice!

On that line of thinking, is it possible to expand the number of slots with C#? Or perhaps create a "custom" piece of equipment, like one that increases the character's statistics on a level up?

Customisation of slots per character/actor (Just like its done with attack and skills for combat in smile game builder) would probably be the best option.

What happens if a game developer decides to include non-human characters. To they have to use the same gear slots as their human counterpart? Why would say a snail character use gloves? Just to give an example.

+1 further on it would be great to have an easy system to link different parts of the equipment to the 3d model if equipped for use. Somehow I am really missing to get new shiny armors displayed on my herp when getting up in the levels .....

+1!

It would be nice if the system would be flexible enough so you could use one different weapon/shield in each hand or a weapon/shield with both hands (like elden ring).

Having more armor slots types like gloves and boots.

Could equip more than 2 accessory (2 feels especially limiting the player options).

Could add one completly custom slot type for exemple :
Passive skills.

Being able to remove slot types per cast, for exemple this cast will never wear a helmet for X reasons.

It would really be great!
