Full agreement.

Git svn needs to recognize a merge for what it is, and has to ignore
the branch which has been merged, looking further for git-svn-id lines
or whatever.  Cherrypicking is harder to contain.  Basically, I think
it is a mistake to use something as fragile as the git-svn-id line in
the log for determining the branch to use for committing.  Instead, a
fixed association of git branches with git-svn should be established.
Even if one needs to write this manually into some configuration file.
Before git-svn does not have reliable information, it should refuse to
commit.  One could specify this on the command line, too: that is a
small price to pay for being sure that one commits where one wants to.

Yes.
