No way. This would waste huge amounts of memory for all the data
structures we want to have parallel to the board, alternatively
require a lot more complexity indexing them.

It's better to continue with a local copy of the board in matchpat/dfa
with the desired properties. It requires some bookkeeping to keep in
sync with the real board, but it's better to take the complexity hit
there than everywhere.
