For me, yes, an example I could use is transforming a generic language using an alphabet, formed using Turkish as the base, and evolving it based on Chinese influences and attempting to adopt logographic styles
This made me theorise on how Chinese works and the absolute role of context, where I could apply it and what not
But what about you?
I would say that 70-80% of what I know about linguistics comes from conlanging. Sure, the basics come up in school, both in literature and foreign language classes but there they are muddied by all the exceptions that real life languages have. In conlanging, we can apply linguistic concepts in their pure form and experiment with them.
