At GIMP 3 era, The Python Script writing style

Operating System: Maybe All

Description of the feature

At the next coming 2.99.8, the Python script will avoid the crash. (See #7106 (closed))
So, One question I have.　　It is not the issue!.

Can I rewrite my own Python scripts by referring to the foggify.py (official one) writing style bundled with GIMP 2.99.8?
Because of I think that the scripting is so far from GIMP 2.10 era... (Too high hardles / So difficult)
Are there any points to be aware of?
Or does the documentation exist for GIMP 3 scripting?
Is it premature? (Is it better to wait for a while? Will some change come?)
