Because usually there is reasonable number of heads, and that is the tags
that might be problem, because the number of tags likes to grow with the
history, perhaps we could pack only tags heads into the pack? This has
additional advantage that tags, especially annotated tags (i.e. true tags
objects) changes rarely.
