Small app size increase in migration from WalletConnect to ReOwn

Is your feature request related to a problem? Please describe.
It appears "CoinbaseWalletSDK" is now added to any project that uses ReOwn, regardless of whether you import or use AppKit. I only use WalletKit but its added to my project, resulting in a small increase. In the near future we are hoping to build an additional product that does require a very restrictive app size (can't go into details). Extra weight like this will determine which features we are able to add to this new product, which we had hoped wallet connect could be added too. Would it be possible to edit the package so that only AppKit users get this package?
