Many thanks you all for the replies!

I have a shortcut attached to "paste>size", so resizing was so easy to achieve:
Ctrl+C then Alt+V(paste>size)
I can't imagine any way to resize (based on other size) easier than "Ctrl+C then Alt+V(paste>size)".

Anyway, I just did an experience. Screencast: http://bit.ly/2T0pmBf
With lock aspect ratio on, I copied the width of the reference image, then pasted into the width of the destination image.
It works for a single image, but to multiple selected images the destination width is applied to the group.
And using my old method "Ctrl+C then Alt+V(paste>size)" I could batch change dozens of images at once.

I'm sad with the so-called "improvement":

By pasting size raster images being croped doesn't make sense. I can't see usage for that, but how I'm start missing the image resizing. Could we ask "dear xara" to review it non-sense behavior?
