Just because the extension is available, doesn't mean you have to use it...
If you want to use Xero, that's up to you. Xero is an accounting program that some businesses use to keep things in order. It is completely separate to Bridge.
We created the extension to Xero as it has been requested by a number of our users, and we take feedback seriously!
If you have questions, feel free to get in touch. We are happy to help.
