When custom database will be disabled for the Free account?

Recently, I noticed that “Custom Database” is available only for the Enterprise account:

At the same time, it’s already enabled in my Free account.
I’m guessing that it will be turned off soon.
Based on this, I’m interested in when it will happen, because I didn’t received any notification.

Its a good Question…

can anyone answer this question ?

I would also like to get an answer to this question. Seems as if a lot of ”paid plan features” if not all are available on the free plan…
