Could requirement to neos/fusion-form be changed to suggestion?

First of all, thanks for implementing SymfonyMailer for Neos. We have quite a few Flow-only projects that need to send mails, and as SwiftMailer is EOL, migrating to SymfonyMailer would make sense.

From reading to code, only https://github.com/sitegeist/Sitegeist.Neos.SymfonyMailer/blob/ba1ae976a3546d465124ec0f5b9bcfe8a7dcc85f/Classes/Action/SendMailAction.php has real dependencies to Neos and Neos.Fusion.Form. Personally I think this could just be a concern of Neos.Fusion.Form instead of the SymfonyMailer package.

But even if you don't agree about this, would you be willing to lower the dependencies so it could be used with Flow only?
