The documentation clearly mention those features aren’t supported as of now.

The Firebase team is aware of that need but it’s very hard to deliver such features at scale.

Firebase is used everywhere these days , so a single change in the platform has impacts in petabytes and massive thousands of cpus load.

I get that it isn't supported. We have followed the recommendations mentioned in the docs but found the usage of these workarounds to be sorely lacking in performance and reliability.
