A good habit, indeed.

When it comes to me, I occasionally mistype nothing for a
letter. So, it'd easily become $ rm -rf ~/ RET, if not such a
habit.

The man pages may not be available in moonhkt's native language?

Options after arguments is not portable [1],
(and btw: incompatible with a terminating "--").

And a few times, when I noticed that it's possible at all, e.g. in GNU,
I (personally) even found that rather annoying - but obviously an "ymmv".

[1] not to confuse with find, which additionally knows "expressions".

Yes, but if so then neither is this NG and I'd think this from the rm man page:

-r, -R, --recursive remove directories and their contents recursively

would be at least as easy to understand as the comments the OP wrote in his script:

rm -f * # remove current directory files
rm -f */* # remove subdirectory files
rm -f */*/* # repeat ...

and the responses posted here. Like I said, I'm just curious about how a
question like this gets posted....

Actually, it doesn't work on Unix systems. It only works on GNU
systems if there's no POSIXLY_CORRECT variable in the
environment.

Also,

rm -rf ./*
or
rm -rf -- *

are better in case some filenames start with "-"

It should also be noted that it will not remove dot files.

zsh issues a "zsh: sure you want to delete all the files"
prompt in that very case (which you can disable), that is when
calling a "rm" command with an argument that is "*" or
"whatever/*"

In zsh, to remove every file:

rm -rf ./*(D)

(The (D) is to include the dot files except "." and "..").
