I think you can now configure it to run in "holy mode". In both modes you can still type meta-x (also via `<space>:`).

I think if you had a very customized emacs setup, you'd have to put some effort organizing it into custom "layers", which is how spacemacs organizes its config and making sure you don't have big conflicts in mapped keys.

IMHO, the layers are pretty easy to put together if you're comfortable with your Emacs configuration. The first one I coded up (for notmuch) was done inside an hour and that's when I was new to Spacemacs.
