Streep to go supporting for "The Laundromat" after all?

Awards prognosticator Clayton Davis from Awards Circuit tweeted this yesterday regarding Meryl's category placement for The Laundromat:

As explained in this week's "Oscar Circuit," award category submissions for Netflix expect to be:

"The Two Popes" (Pryce in Lead, Hopkins supporting)
"The Laundromat" (Streep is supporting and comedy)
"The Irishman" (DeNiro lead, Pacino/Pesci/Paquin supporting)

While historically Davis isn't necessarily super reliable with info such as this, some at Awards Watch are suggesting that he's correct, in that he may be privy to Netflix's official submission plans.

Supporting seems the more likely category for Meryl, considering what we've heard so far of her screen time and the overall length of the film. This placement also makes it more likely that she'll actually be nominated.

Might we see Meryl up against Laura Dern for both TV and movie awards next year (both for their work in Big Little Lies and Dern for her supporting role in Noah Baumbach's upcoming Marriage Story)?
