There is no harm, because AFAIK svnadmin deltify has been redundant
since before 1.0 came out. SVN performs deltify automatically when you
commit.

Also when manual deltify *was* necessary, you couldn't just deltify HEAD
at the end of the day. You had to individually deltify every new rev,
usually in a post-commit hook. Something like:
svnadmin deltify -r $2 $1 &>/dev/null &

You could also keep track of the last rev deltified and do something
like the following in a cron script:
svnadmin deltify -r $last_deltify:HEAD $repo_path

Hope this helps...
