KeyFrame is not sent if no changed values about ua-.netstandard HOT 1 OPEN

Following up on this issue,

https://reference.opcfoundation.org/Core/Part14/v105/docs/6.2.4
The KeyFrameCount with DataType UInt32 is the multiplier of the PublishingInterval that defines the maximum number of times the PublishingInterval expires before a key frame message with values for all published Variables is sent. The delta frame DataSetMessages contains just the changed values. If no changes exist, the delta frame DataSetMessage shall not be sent. If the KeyFrameCount is set to 1, every message contains a key frame.

Can we have an option to choose sending key frames or delta frames when there are changes?

E.g. when the option is set to TRUE, the behaviours change from:

the first: key frame
no changes: not sending
no changes: not sending
changes: delta frame
no changes: not sending

To:

the first: key frame
no changes: not sending
no changes: not sending
changes: key frame (not just changed values)
no changes: not sending

I tried to override internal class MqttPubSubConnection : UaPubSubConnection, IMqttPubSubConnection, but it is defined as internal unfortunately.

Thanks.
