WORLDEDIT-2718 - Reported by xehex

For this example, we'll set chests as a disallowed block in the configuration file of WorldEdit;
disallowed-blocks: [54]

After reloading the server, join the game and place a chest. Use /tool repl 1 to set the block replacer tool to stone, or a block that is not disallowed. Then, punch the chest with the replacer tool. Chests are now bound to the replacer tool, and can be placed with WorldEdit. This works with any block.

most things can do that
the disallowed blocks is only for parsing, eg if you tried //repl 54 instead of //repl 1
disallowed blocks is a rather old config option and the functionality you are looking for belongs somewhere else, so as masks
