For Corel Corp.
When you develop something like x7 it would enhance the user experience greatly if when users had to save as old versions. you would have the save as function BY DEFAULT automatically set the correct functions for the closest possible save and present an options table for all items not directly saveable or convertible.
That is the first thing we check with any new software and always discover little things not to do for saving .
You have the knowledge to do it by default.
Think of users, a lot of us test and read documentation, most of the questions in this forum are from those who don't and all of us would like not to have to.
Thanks

The problem is that a lot of people would want it to default to "best representation" and a lot of people would want it to default to "best future editability". But you can only default to one or the other, not to both.
