I get where you're coming from.
But there are many, many, services like this that I suspect people would like functionality out of the box for.
So which ones do they build functionality for? Strikes me more as a nice to have as it doesn't add anything much functionally to TestComplete itself. Just makes an easy interface for the small subset of people who happen to use Google Drive for storage.
And given that most of them provide the tools for people to tailor their own solutions, so it's not currently a dead end, I can't see it getting priority any time soon.
I'd rather have not had to write my own TFS plugin. But if it's that or nothing? And by writing a plugin you would be focusing on testing work as you'd use said plugin for testing purposes .... :smileywink:
