There has been so much valuable info posted here over 3 years.
It should be a simple thing to implement for users that want to sync all the features of Biab with any DAW.

To get all the Biab features in an actual Plugin you would need a crossplatform programming language like JUCE to allow the code to be used in a standalone Win Mac version and a Plugin Win Mac version.
This was suggested back in 2015 for that very reason.

Here we are 8 years later with BB & The Workarounds still.
It was bad enough going all those years trying workarounds for the missing VstTimeInfo that syncs vst's like Ezdrummer to the host.
