Github user bbende commented on the issue:

Actually, I take back my last comment, I now see where the value is
obtained and it does have the logic:
```
String propertyValue = propertyDescriptor.isExpressionLanguageSupported()
?
context.getProperty(propertyDescriptor).evaluateAttributeExpressions().getValue()
: context.getProperty(propertyDescriptor).getValue();
```
Sorry about that.

> I have the use case where I have two separate NiFi clusters reading data from
> the same topics but need to have unique group ids so they each get separate
> copies of the data. It would be useful if the group id field supported
> expression language so I could use a processor group variable to define the
> group id to use. I have a large enough number of kafka consumers to make
> this tedious to manually change.
