Delete profile attributes

+1,000,000
This issue has been around since the days of the mbox dropdowns.  One call to 'lazy load' into the dropdown and then the name is there forever.  Dev makes a typo in the naming convention.. and now it is forever available to erroneously select the wrong one.
I LOVE the easy 'lazy load' to use the fields, but there has got to be a more efficient method to clean up the errors and outdated fields that build up.

when could we expect a fix for this? I mean, having an option to delete un-used parameters

+1 from me too. As mentioned by the other contributors, there are so many relevant use case where it would be relevant to be able to delete this.

It would be really useful to force the removal of old attributes.

Use-cases:

- Old parameters that were added during development

- Parameters where the name was changed on behalf of our customers

Is there even a way to reset them? This makes everything so difficult to test. 

Note that while it's apparently still not possible to delete profile attributes, via an offer one could reset the profile to some other value or to an empty string. For example:

adobe.target.trackEvent({

'mbox': 'YOUR-MBOX',

        'params': { 'profile.YOUR-ATTRIBUTE': '' }

});

Definitely a handy feature to have!

+1 from me, I know there is interest out there from many about exactly this.
