Yes, specifically an empty one.

Should do:
$ for v in 24.5 25.3 26.3 27.2 28.2 29.1; do
    emacs-$v -Q -batch \
      -eval '(message "%.2s %s" emacs-version (make-hash-table :size 0))'
  done
24 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8 data ())
25 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8 data ())
26 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8125 data 
())
27 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8125 data 
())
28 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8125 data 
())
29 #s(hash-table size 1 test eql rehash-size 1.5 rehash-threshold 0.8125 data 
())
