Great, I think this was my first keysend transfer actually! It feels unfamiliar doing Lightning transfers without invoices / interaction, but also super practical and cool!
Now we just have to let people know that they can use this e.g. to easily receive donations privately. So much better than needing to set up or even develop a dynamic website that has a connection to your node and fetches a new invoice every time.
Not to speak of increased security by not having to expose the node more to the internet.
