BUG: Import emails users – even when told NOT to

I was attempting to transfer my userbase from my live site to my development site.

I exported from the live site to CSV (using Cimy).

Then import the CSV into my dev site (using Cimy), MAKING SURE both Email notifications were unchecked.

Send an email to the new users created. UNCHECKED
   Send an email to the existing users with the new password. UNCHECKED

But it emailed all my users, anyway, with:

This notice confirms that your email was changed on [SITE NAME].

   If you did not change your email, please contact the Site Administrator at [ADMIN EMAIL ADDRESS]

If this email was generated by Cimy, why did it send it if the settings were unchecked?

If this email was generated by WP, why does the setting even exist in Cimy if the plugin can not be prevent the email?

It was bad news that a) my entire user base was emailed, requiring a follow-up email to tell everyone nothing has changed, and b) my low-volume, low-resource development email server was hammered by all the emails.

Fix by either coding the plugin to prevent WP from sending the email if the settings are unchecked, or remove the setting (preferably replacing with a message warning that WP will send emails to all imported users) so that admins are not given a false sense of security.
