Yes: Choose key names for your scheme that aren't already in use and are
clearly different from existing keys.

That is, they shouldn't start with "addr:" - that prefix is commonly
used for tagging addresses in a way which can actually be parsed
properly and doesn't rely on guesses by human observers.
