I think that a "?cron=go" is probably sufficient, as long as the cron is 
executed as frequently as wp-cron needs.

My suggestion would also be to store the last time wp-cron was executed 
via "?cron=go" in options.  Pseudo-cron would not be triggered if the 
option had a time stored for the last "?cron=go" request that was more 
recent than the required minimum duration between cron executions (15 
minutes?).  That way you can avoid a user option for turning off 
pseudo-cron AND have more reliable execution for when cron isn't working 
or is improperly configured, since pseudo-cron would execute if a 
scheduled cron was somehow skipped.
