If you are trying to delete a word/symbol while the current symbol is a electric pair then it should delete the pair instead leaving another pair.

For instance,

([Cursor Here])

If I try to backspace the ( open curly bracket. The common behaviour for backspace will delete both open and close curly bracket. But if I try to C-<backspace>, which it is backward delete symbol; then it will only deletes open curly bracket and it leaves the close curly bracket behind.

I think it may be good if it can trigger electric backspace if delete word/symbol occurs in this scenario.
