Don't now how many out there appreciate the 'subtree merge' behavior, but
in our and our clients, a potential scenario of tenths or hundreds of
developers branching&merging at any level of source tree will become a
unmanageable version control system, in addition to a confusing user
experience for the most of developers.

Take a look to this snippet of a unix/bash pre-commit hook, just in case it
inspires you:
Disclaimer: We donĀ“t have any measure of performance of this script. We
simply haven't need to measure it yet.

# Check forbidden mergeinfo paths
TXN_PATHS=$($SVNLOOK changed -t "$TXN" "$REPOS")

# Grep for paths *not* in merge-allowed levels: /trunk,
TXN_PATHS=$(echo "$TXN_PATHS" | grep -Ev "^....trunk/?$" | grep -Ev
"^....branches/release/\w+/?$" | grep -Ev "^....branches/feature/\w+/?$")
  ELEM_PATH=$(echo "$TXN_PATH" | cut -c 5-)
  MERGEINFO=$($SVNLOOK propget "$REPOS" svn:mergeinfo -t "$TXN"
"$ELEM_PATH" 2>/dev/null)
  if [ ! "$MERGEINFO" = "" ]; then fail_forbidden_mergeinfo_path;fi
