This turns off all _built-in_ implicit rules. It doesn't turn off any
implicit rules that you define yourself.
I think this is pretty clear in the manual. If not, please let me know
what you find confusing.

This turns off all the builtin suffix rules only; it doesn't turn off
the builtin pattern rules.
However, almost all the builtin rules are suffix rules, so this gets
most of them.

There is no speed difference; the difference is that setting an empty
.SUFFIXES doesn't get _all_ the builtin rules, just most of them. The
-r flag gets all of them.

Not so; see above.
