Can I develop paid GitHub App & distribute outside of Marketplace?

As the title states.

I’m new to GitHub App development. I watched a GitHub presentation on YouTube where they urge developers to use the Marketplace and the GraphQL API - cool. That video was also pre-Microsoft acquisition. I also reached out to GitHub Support via email, their response indicates they’re “revamping the paid app verification process” and it sounds like they’ll be “sharing updates later this year”.

Has anyone on this forum recently created a GitHub App intended to be a paid service (aiming to make a business out of it ) ? Is it still possible?

Thanks all,
