Hi, author here.

Yes we have many large companies (Fortune Global 500) down to small organisations using our software with this kind of interception (see for example https://cuno.io/about-us/). It took us a decent sized team a lot of years to get right, because it is so very hard a problem to crack. But we think it is worth it. And for those who don't want to use such interception, we do offer a FUSE layer as well that still offers much higher performance than alternatives.
