Yes, in fact we can only do it like this because logical and physical type
are the same. Otherwise, we would need to adjust the index.
I'll clean up `RowSchema` a bit more to remove the distinction of logical
and physical types.

> After a [discussion on the dev mailing

> I propose the following changes to the current handling of time indicator
> attributes:
> * Remove the separation of logical and physical row type.
> ** Hold the event-time timestamp as regular Long field in Row
> ** Represent the processing-time indicator type as a null-valued field in Row
> (1 bit overhead)
> * Remove materialization of event-time timestamps because timestamp is
> already accessible in Row.
> * Add {{ProcessFunction}} to set timestamp into the timestamp field of a
> {{StreamRecord}}.
