Comment (by canduruk):

 Hi @swissspidy — wanted to check in here. What would be the next steps to
 get Felt included in this allowlist? Thanks a lot in advance for your
 consideration.

 While that's technically possible for you to add, it also complicates
 things :-)

 These folks don't have access to the plugin system or aren't tech-savvy.
