In large part because the transaction log is basically a reimplementation
of a database, and we're not a database project.  In large part because
it's not trivial to create a domain object that modifies the txn log for
free.  In no serious part because it's named "Transaction" log ... how
could you put anything else in there... ;)

Does any other app handle undo this way?  Why should gnucash be different?

What does gnumeric do when you undo a change not on the local workbook
page/tab?  We should do that.

Of course it is possible, anything's possible.
