There are at least 3 standards for the + shape already. Phillips, Pozidrive, and Japanese Industrial Standard (JIS). They do not play well together.

I have a “running sink water at bedtime” cat, and an “I demand to drink ‘found’ water outside at first light” cat. We still miss the shower curtain licker.
Nevermind the 5 other dishes in various rooms including a never ending cat fountain they used all of a month before scorning.
Haven’t read the book yet, huh?
They’re required by some dog boarding/daycare places.

Here’s another take from someone who won a Pulitzer for the times.
Also the subject of Cory Doctorow’s “Down and out in the Magic Kingdom” from 2003.

Should the slot be partial or go all the way through? If partial, is that standard for the size of the screw, or universal?
How wide should the slot be? Should that change based on the size of the screw?
How deep should the slot be?
Should the sides of the slot be perfectly straight, or angled to perfectly fit the wedge shape of the driver? If angled, what angle?
Should the bottom of the slot be perfectly flat or slightly rounded so a coin or something could be used in a pinch? If rounded, what radius?
Should the top of the screw be perfectly flat, or domed, or raised?
Should the bottom of the head be flat, angled (at which angle), smooth, rough.
Should we use metric or freedom units for the thread pitch?
Should the threads go all the way to the head?
Should the point of the screw be flat or tapered (at what angle)?
Ok, only the first half of those were about the driver used, but I’m sure there are things I missed in that!
