Bang methods are not usually used for that in Ruby core and stdlib.
I agree for the practical point of view of this though.
I'm unsure what a good name would be.

Using mkdir_p for this seems a bit dangerous, as it might create intermediary directories you did not intend to.

How so?

I found that often write 
Dir.mkdir(folder) unless Dir.exist? folder
and similar code for rm, rm_rf and so on
We can simply make bang-versions like
def Dir.mkdir!(folder, permissions=0744)
  Dir.mkdir(folder, permissions) unless Dir.exist? folder
# or another alternative  Dir.mkdir(folder, permissions) rescue false
end
