How is the situation with Cocos Store plugin sales? Wondering if it's worth the time and effort to invest into making paid plugins

Is there some kind of data or analytics about overall interest of buyers of different plugins?

I know this information could be hidden from end users, but maybe there some info about the topic?

I like developing modular solutions and extracting them to plugins, but I don’t know if it can be of any financial interest to publish them to get some coin for the job.

I see several plugins there, that seems kinda popular, but they have not that many reviews implying that they are not that successful in money sense.
