Rm should really do something more sensible on the -i switch, like displaying a summary or the files and asking for confirmation only once. Personally, I like to run "find -name file" and once I'm ok with it, I circle the command back and add -delete to it. It is much more usable.
alias rm=‘rm -iv’

Your ‘find -delete’ trick does the same: it creates time to think between expressing yourself and evaluating the outcome. This is great.
