Hopefully, although there are challenges to overcome. CT is a fast-moving ecosystem, with logs coming and going, and policies changing regularly. This requires CT-enforcing clients to be very on-the-ball with updates, both in the sense that the developers need to pay attention and update their code in time, and any users of the apps need to upgrade frequently. Browser makers can handle this because they are competently-staffed and well-resourced. The authors of non-browser apps need to know what they're getting into.
A cautionary tale: there is a library for adding CT enforcement to Android apps. Earlier this year, every app using this library was suddenly unable to establish any TLS connections because Google stopped publishing a JSON file which the library should never have been consuming in the first place. There was plenty of warning that this would happen, but the author of the library was not on-the-ball. https://groups.google.com/g/certificate-transparency/c/38Lr9...
