Deleting remote branches with git-branch and reflog questions

Hello,

As per subject.

If anything, these are safer to delete than local branches because they will be restored automatically with the next fetch, so why do we require the extra switch for remote branches?

Would it be simpler for the user if the following worked?
$ git branch -a
* master
  origin/master
$ git branch -D origin/master

i.e. that the -r switch was unnecessary in unambiguous cases.

reflogs -------

Why does the reflog directory .git/logs need to store the refs/ directory? Aren't /all/ the refs under "refs/" these days?

Is it right that the reflog for a branch is deleted when the branch is 
deleted?  Doesn't this kill one of the advantages of reflogs?  In particular, 
if I accidentally deleted a branch, I would have no way of getting it back 
because the reflog has been deleted too?  Personally I'd prefer that a reflog 
line was added saying
  XXXXXXXXXXXXXXX 00000000000000 Deleted
Or similar.  After all; it's only disk space.  If the ref was later created 
again, then the log can continue to be added to, but it will have a "Created 
from" in the middle instead of at the end.
