Please create a sync setting that forces Contacts/People to only sync one-way. In other words, I only want data to push from the server to my Android device, and not vice-versa. If I create a brand new Contact on my Android device, then that can sync to the cloud, but lock existing Contacts on my Android device so that I can't edit them.

Why? Well, your Contact sync engine is not reliable yet. In fact, it's screwing up my precious data. This is totally inexcusable. Want a case study? OK, here you go...

I was so excited when you added two-way Contacts sync between my Exchange data and Outlook on Android a few months ago. Unfortunately, the first thing that happened is that Android wiped out / deleted the body text field of data on thousands of my Contact records. Ouch! I had to resort to backups to recover my data that I have spent 20 years building. So, I naturally disconnected my account from Outlook on Android, and figured I would take another run at it in a few months. Well, I did that. The good news is that it didn't delete my body text this time, but it messed it up certain notes that I had in my records. In the body field of my records, if I had an email address such as "You@Microsoft.com", it took it upon itself to reformat that as "You@Microsoft.com<mailto:You@Microsoft.com>". NO! I don't want that!! It screws up things big time for me. Don't change my data!

...OK, now please don't tell me to submit this to Help. I have already done that. This is not a troubleshooting ticket. This is truly a suggestion to allow the user to only allow one-way Contact/People syncs from their Android devices until we can trust that your sync engine is rock solid.
