I guess fido-mode sets `completion-styles' locally in order to achieve
ido-like defaults, right?  But as a user with customized
`completion-styles' and `completion-category-overrides', I wish there
was a simple way to just use them with fido, too.  Especially, I can't
see how I could figure out the right category override.  Is the
completion metadata accessible in icomplete-minibuffer-setup-hook?

I would like to use fido (more than icomplete) because the keybindings
suite my intuition but I'd like to keep my completion styles and
overrides as I have them.

Bye,
