I agree that it would be a shame, we are continuing to look into the problem and hopefully will be able to find a solution.
on your comment about upgrading to Creative Cloud, this would not require you to also purchase the MySQLi extension at this time. you can use the DW CC 2014.1 without the MySQLi extension. I can't speak to future versions of DW, but the current DW versions don't require MySQLi. Also, as a part of the Creative Cloud subscription, it gives you access to older DW versions. the Creative Cloud application manager allows you to install DW CS6, CC, and CC 2014.1:
