BUG: Open with option missing for M4A / ALAC files (OSX)

I just discovered this incredibly frustrating bug while starting to work with M4A / ALAC (aka Apple Lossless Audio) files. Right clicking on such a file and going to the 'Open With' menu, Audition is missing from the list. However, manually opening the same file via dragging it onto the Audition icon or program while open, or even via the Open Audio command in Audition all work just fine. These M4A files are directly converted from iTunes. This is running Audition CC 2014.

After some researching, I discovered the reason why. The Info.plist file inside the Audition.app -> Contents folder apparently is missing a CFBundleTypeExtension section for M4A files. Open that file and do a search for 'CFBundleTypeExtensions'. You will see a bunch of entries for that kind. Basically, this piece of information tells OSX what extensions/filetypes Audition can open.

Example of the mp3 filetype:

	<dict>
		<key>CFBundleTypeExtensions</key>
		<array>
			<string>mp3</string>
		</array>
		<key>CFBundleTypeIconFile</key>
		<string>au_document_secondary_mp3.icns</string>
		<key>CFBundleTypeName</key>
		<string>MP3 Audio File</string>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
	</dict>

So following that logic, I created a duplicate right below it for M4A:

	<dict>
		<key>CFBundleTypeExtensions</key>
		<array>
			<string>m4a</string>
		</array>
		<key>CFBundleTypeIconFile</key>
		<string>au_document_secondary_m4a.icns</string>
		<key>CFBundleTypeName</key>
		<string>Apple MPEG-4 audio</string>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
	</dict>

Save the file, either restart the computer or rebuilt the Launch Services database and restart OSX, and viola, now when right clicking an M4A file, Audition is an option!

What I want to know from the Adobe Devs is, why is that option missing in the 'Open With' menu to begin with, and will it be fixed for the Audition update?
