You're right, I should have been more precise.
I was referring to Pavel, Enric, and myself. Pavel had this opinion here:
https://lkml.org/lkml/2019/4/4/1040. I don't know what Pavel meant by "we"
in that comment, but I would guess that could mean the other LED maintainers
as well? I talked with Enric 1:1 and he didn't see the problem with changing it,
though perhaps he was only considering our use of the LED via powerd,
and not users in general. I'm guessing Pavel's and Enric's meanings though,
excuse me if I am misinterpreting.

Would it make sense to keep the old name as is, and only make the new
Wilco name begin with "platform:"? What would you think is best?
