Hello,

Could anyone tell me why growing the selection rounds the corners?

Hi!

Because the algorithm is generic and does not attempt to retain any special geometrical properties of the selection. Keep in mind that the selection is essentially just a channel.

Could you add this feature?

Any feature that makes sense can be added as long as someone writes the code. I think your use case makes sense and one way to support it would be to add a check box to the Grow Selection dialog that if checked would only grow the selection in the x and y axis.

Or rather: First the x-axis and then the y-axis.

Another option would be to let people specify the morphological mask it uses for the grow operation (I assume that's how it's implemented). A square mask would preserve corners in rectangular selections, I think.
