The real question is “should default behavior of scaling images be fixed or arbitrary aspect ratio?” The answer is clear. No one will be confused by default behavior matching the most frequent use.
I really wanted to use LO writer to design all the text in a book but the program is laden with bugs and lacking in features, which left me deflated. (not imagescaling but many other problems).
LO is a fantastic idea that suffers from teething problems well into its teens. The reasons to use any program over others is its ease of use, stability and reliability. I think LO is on the right track in terms of ease of use, save a poorly written manual and few quirks, but stability and reliability are not there. If those who help create it stop defending or ignoring bugs and poor design, LO will become a standard, the way Linux did.
