CrowPi-L future suggestions

Just a couple of suggestions for future CrowPi-L type designs -
1. I'd buy a new version with Pi-5 support in a heartbeat!
2. While the "L" isn't an experimenters machine like the 1 and 2, it would still be fantastically useful to have a GPIO header exposed internally. I've bent, broken, and mangled this poor computer trying to get power, ground, and gpios for internal functions.
3. The use of a usbc type connector with 12v-only scares me. I'm always worried I'll plug the brick into another device. Barrel connectors would be safer, and more standardized. Of course, USB-PD would be even better...

Feel free to ignore, this is just what I've run into with the L, which I love!
