Scripts no longer break for duplicate mappings!? what?!

It seems that one of the most annoying errors for our scripts may have been squashed by Ableton.
Recently I was busy breaking scripts on purpose so that I could update our tutorial on how to fix a broken script with the different error messages Ableton spits out. http://remotify.io/docs/how-to-fix-midi-remote-script#assertion
In the past, attempting to give an input on a controller more than one function (i.e. to control both volume and pan) would result in a broken script due to the lovely 'registered twice. Check Midi' error. http://remotify.io/docs/how-to-fix-midi-remote-script#assertion
This must have quietly been fixed by Ableton as I could add multiple functions to the same control without any issue!

As yes I don't know which version of Live it was fixed in as I couldn't find anything in the release notes but it poses a dilemma. App currently has a lot of checks in place to prevent you from creating duplicate (midi message) mappings and breaking scripts.

So I can prioritise this, my question to you all is how useful would it be for you to be able to have multiple functions assigned to one input on your controller?
Don't forget that we have modes for adding multiple groups of mappings too http://remotify.io/docs/tutorials/do-8-times-more-with-Mode-and-Shift
