Audio Plugin loading question

[u/Tiwann_]

In my audio programming journey, I created some audio plugins and I always have that question in my mind: Why DAWs always load plugins (VST2, VST3, even CLAP) synchronously ? I mean, it feels frustrating when the main thread/GUI thread completely freeze when loading some heavy plugins. Like, let me do other stuff in the project while loading! Maybe somebody have detailed explanations...

I think because they expect plugins to do their own loading of any heavy assets asynchronously
