PLEASE CHECK THIS OUT. Our own Aeronmelon is going through some shit at the moment and could use some help. Check it out here and consider an upvote or a comment to push it into activity. Sorry, not something I do often or will be spamming. But I care about my friend and if I can get a couple more eyes on his situation then I'm going to try to do what I can.

Wouldn't that make the face on the right non-planar?

If you’re free to put the center vertex anywhere, then I’d think you could position it to avoid that…

That scutoid (possibly all of them, I don't know) is just a pentagonal prism with a corner cut off.

Cylinder side also non-planar, yet not a problem. Paper sheet area does not change when curved.
