Williams played as an unseeded competitor at the 2018 BNP Paribas Open and at the 2018 Miami Open.
She was not seeded at either tournament. Likewise, it's a scary prospect for the top-ranked players who may have to face Williams early on.
The American is expected to play at Roland Garros next week, where she has won the title three times in the first round, but without being seeded she could conceivably meet champion Jelena Ostapenko or any other top seed in the first round.
While Williams can enter Roland Garros under the WTA's protected or "special" ranking rule, it's up to Grand Slam organisers to give her a seed.
In a statement to the AP on Monday, the French Tennis Federation said, "This year again, tournament officials will establish the list and ranking of the women's seeds based on the WTA ranking".
Some players may have not been supportive in the past of such a change to the rule, but more recently, a few prominent competitors have offered differing thoughts.
"She obviously comes back to win and the wait has been long, so she will probably start Roland Garros with a mix of stress because she will want to do well and excitement because playing those events is the reason why she made such huge efforts to come back", he said.
However, this past year the WTA adjusted the rule so that absences for maternity leave are treated the same as those for injury and illness by providing all players a two-year window to begin using a special ranking, plus an additional year from the date of return to utilize the special ranking.
"It's normal to give birth", Halep said, via The Washington Post's Des Bieler. "It's normal to have protected ranking ... it's more than tennis", Halep said.
Serena Williams 'very likely' to get seeded at Wimbledon
"I remember doing an interview when Serena was pregnant and people were asking me constantly, do you think she can do it?"
Several of Williams' rivals were critical of the rule that doesn't protect a ranking when a player takes maternity leave.
Even Serena Williams can't avoid the mommy track.
"It's not as if she left because of injury and lost her passion for the game", Blake said.
"She was number one so she deserves seeding."
Mouratoglou further revealed that Williams' comeback was impromptu because she was not 100 per cent fit, though the return helped to show how much work needed to be done on the training ground.
A CT scan revealed blood clots in her lungs, and subsequent coughing fits ruptured the stitching from her C-section, causing hemorrhaging that was aggravated by the blood thinners she was taking.
Williams, who has won 23 grand slam singles titles, is world ranked a lowly 453rd having returned this year from having a baby.
"Proud to participate to keep the sport clean". "Even if they do test me at my current ranking of 454 in the world".
