Question about VST3ClientExtensions

I’ve been looking into using the VST3ClientExtensions for a project, specifically Presonus VST3 Extensions. , but I need a little bit better understanding of how they work.

I don’t have the proper phrasing probably, but does implementing one of these extensions into my project guarantee my plugin could use it in every DAW that supports VST3 ? Or is it per DAW depending on if they provide the proper interfacing to use an extension like this? I know for example that info like AudioProcessor::TrackProperties is not really gaurenteed to be provided in every DAW, so I assume it’s similiar with a VST3 Extension?

Any input would be appreciated!
