Interesting. I havent seen anything related to it from anyone. I have literally never used it on Android so no big deal to me either way. If someone wants to track down a commit cool or if I run across one Ill add it but Im not losing sleep over it.
Sure your rom your priorities 
Just was pointing that out because I tested your rom and the hotspot is a feature I use every day on my car. So I noticed it was broken and decided to shout out a warning in case you didn't know.
Is it working on other Roms?
The hotspot? Yup, works on every single one. Tested it already.
You can try to pick/find their commits because they got it working. I believe it's related to the data connection because that's what's not letting it turn on.
New build up. Pretty sure the VOLTE issue is resolved (works for me at least) and the network connection on reboot is fixed (for me) as well. This build has a bunch of kernel changes, build optimizations, and fixes added. I would recommend clean flashing again.
WiFi hotspot is still broken. If you have data connection on it doesn't turn on, if data is off it turns on fine. Same behavior as in the first alpha build.
But keep up the good work. You have the best pie rom available, the brightness slider works fine, not broken like in all other pie roms where it doesn't go dim enough.
