I meant support in a more direct manner. For example, writing a piece of software that does better Markdown importing to Notion.so. You're only enriching Notion.so's system, you're at the mercy of their API, whims, and bugs.

There is no black/white category of what is direct support though. It's a spectrum. And these are my own personal heuristics, rooted in my experiences and found benefits/drawbacks of my own projects and working with people.
