One of my family members got into the “blue-green algae” fad (about 5 years after it fell out of mainstream). It was too expensive so they bought the horse algae from veterinarian supply. He said it was exactly the same, as long as you could put up with the grit.
These people exist (and I’m related to them).
I’m in the same boat. I love that it makes self hosting easier for me. It does what I need and even gives me a small extra measure of security. I admit, I use it because I’m lazy, I could do it without Cloudflare and do for some services. So, I figure if it truly becomes urgent or intolerable I can drop it from the stack.
