I believe those are all trademarked. Unicode tries to avoid those.
> A spray can to represent spray paint, insect spray, or spray lubricant.
Interesting idea! I wonder if there'd be any interest in getting wider coverage of other bitmap paint tools: rectangular selection, lasso, paint bucket...
> There's a power plug but no power socket.
That's problematic from a localization perspective, as electrical sockets vary widely from country to country, and some of them may be difficult to recognize as a socket at a small size. For example, some European countries use a socket which is made of three circular pins in a straight line -- it'd just look like an ellipsis.
Besides, there isn't a lot of symbolic meaning that's conveyed by a socket that couldn't be expressed just as well with a plug.
> There's no staples or stapler.
Maybe. There isn't a lot of symbolic meaning to these either, though.
> There are no appliances—no oven, microwave, toaster, mixer, washer, or vacuum cleaner.
A lot of those will just look like white boxes at text size, and -- again -- they don't have a lot of symbolic meaning.
You might be able to make a case for an upright vacuum cleaner, though, since that's visually distinctive and is associated with cleaning.
> There's no traffic cone.
Oh, I like that idea. It's got some symbolic meanings, too, like "warning" and "under construction". There is already a construction sign (U+1F6A7), though.
To be fair, a lot of existing unicode points don't really have a semantic meaning either. Eggplant only got a semantic meaning after becoming a part of unicode.
