I disagree. What we've done is bound two completely different
operations (one "unsafe", one not) to the same subcommand, causing
folks to make close mental associations that shouldn't be made.
Instead of letting folks mentally divide subcommands into those which
are and aren't part of daily life, are and aren't "unsafe", we've
mixed a branch-based development operation with a likely uncommon
oh-my-god-they-moved-the-server-and-i-need-to-fix-my-wc operation.

And the command count is completely unrelated to the learning curve.
Should we have gone the following route for the sake of making
Subversion "easier to learn"?

   svn fetch ### for cat
   svn fetch --make-wc ### for checkout
   svn fetch --install ### for update
   svn fetch --install --from ### for switch
   svn fetch --but-no-really --from ### from switch --relocate

No.
