As there was no reaction whatsoever, I issued the icon request in their github.
If that was uncalled for, please tell me so and I will delete it immediately.
Otherwise an official media kit might prove helpful, or at least a reply granting this operation.
I kinda like this. It’s a shame no one from the team has responded yet. (I’m just no one, btw.)
I’ll try pinging @core-devs and hopefully at least one of them would notice your effort and give permission. (I’ve also put the logo you submitted on simple-icons GitHub issue.)
