Customer Support / Technical Support does not get to make decisions about whether or not to enable free realm migrations or anything like that.
If you want to suggest that as an option, it would be best to make a thread about that on the #community:general-discussion forums where it can be seen by the WoW team / Community team or on the #area-52 forums. The people that make those decisions don’t look to the Technical Support forums for feedback or suggestions unfortunately.
