NOT IGNORE sounds counter-intuitive... Can we use ADD/REMOVE instead?

admin capture bindings remove table t1;
admin capture bindings remove table test.t1;
admin capture bindings add table t1;
admin capture bindings add table test.t1;
admin capture bindings remove database db1;
admin capture bindings add database db1;
admin capture bindings show;

The capture filter is acting as a blacklist, so we need a negative keyword. The not ignore is to remove the item from the blacklist. If we use add / remove, users may think that only the added items are considered for baseline capture.

Ok. Another question: is it possible to use a system table to represent the blacklist(like mysql.expr_pushdown_blacklist)? One of the advantages is that we can use INSERT/DELETE/SELECT to show the list, which is easier to learn.

Alright.
