This is the expected behavior and not up for debate.

Consider this use-case, for example: You keep a private patch or two on
top of upstream, and you also regularly pull from upstream. You get this
history:

  ---o--o--o--o--o--o    <-- origin
      \     \        \
       A--B--M--------N  <-- master

A and B are the private patches. From time to time you want to update them
if they get out of date, which is indicated by merge conflicts in the
merges M and N. Then you want this result:

  ---o--o--o--o--o--o         <-- origin
                     \
                      A'--B'  <-- master

i.e. linearized history without merges.
