Hi, English isn’t my mother tongue so I was asking myself that question since I first encounted a w/… Back then I was like: “What tf does ‘w slash’ stand for?” And when I found out I was like “How, why, and is it any intuitive?” But I never dared to ask that until now
Because, as you probably just noticed, it’s sometimes part of a sentence, used without the name. Maybe I’m texting “Dr says it’s not a tumor, I’m pregnant” or something.
In addition, Dr (w/ or w/o .) sometimes means Drive, and USPS sorting machines prefer no dots, so that might also drive autotype to choose dotless, or at least offer it.

In formal communication I would type it out, but not, for instance, texting my kids with updates on the cat or their dad or whatevs
