TLDR
Apparently if you delete your google account as an only admin of a workplace by just clicking remove account on expired subscription screen when you are on document page you not only loose access to google workplace but also you can create new workplace google account using same domain and email immediately and it’s fresh google domain account without domain verification and with everything wiped off from your old account. So you don’t have access to anything but on the other side there is possibility to use gmail as spam hub if google fucked ip something in their dns verification and once verified and after that expired domain gets bought again it stays verified.

Well I luckily migrated my gmail to other provider 3 years ago and I lost nothing important there but lol.

You can easily lock out yourself from your domain.

I opened ticket using some questionnaire and by adding another dns txt record to my domain to claim access to workplace admin page and let’s see what they do.

If they ever respond to that ticket and how long it will take to get it resolved.

This is good test to see if google is still a people’s company or an evil corporation.

I was using workplace as long as it was free from days of google app engine and begging of cloud revolution. I remember at best times I could chat with google support employee about spam I got from domain registered on google servers and he was processing ticket for me.
