Females have their role, like when protecting other females. They can go into say the womens restroom and it's not as obvious that they're SS or there's no need to clear the entire restroom because male SS will be entering.
I forgot the YT channel, but there was a female SS agent talking about it. Business Insider or GQ something like that.
BS.
A man is more than capable of going into a women's restroom. Just tell anyone there, "I identify as a woman." It's how it's done now.
But seriously, if a male janitor needs to clean a restroom, they open the door, announce they are coming in, and wait for anyone to respond they need a minute.
Not necessary to provide a government salary and benefits to lots of women just to clear a restroom.
I disagree with the view that you don't need to clear the restroom. Too many directions for a threat to come at you. Plus too many places for someone to hide (stalls). One female agent protecting someone in a busy restroom is a huge risk to take.
I can think of 4 scenarios off the top of my head, each having to do with a busy restroom vs. an empty one. Empty is so much easier to manage. And, yes, there can be a female agent to make it less embarrassing for the protectee to pee as opposed to a man listening. But a male ought to be stationed right outside telling people to use another restroom or wait.

Regardless of the restroom excuse, they still need to provide capable protection agents.
Consider this: don't assign protection detail members based on gender. do it based on what type of threats they might encounter.
Even if the women assigned can physically shield the principle from a gun fired near them, can they take on an assassin via hand-to-hand combat?
21 foot rule should apply to these situations. You can't rely on a firearm all the time. Need time to draw, clear line of sight, etc. In a crowd of people (shaking hands, asking for autographs...) the principle needs someone capable of protecting them from immediate threats within a few feet. Might need to strong arm a person trying to shove a knife in the protectee's ribs.
Seems like common sense to me.
