My wording could have been better - I meant that it’s uncommon for engineers to know both iOS and Android at a deep level. Sharing code can let you share a lot of your logic, but you still need to understand the native host environment well, in fact maybe even deeper than normal since you are using unconventional approaches. So you need engineers that have this deep iOS experience, deep Android experience, and deep C++/rust experience. If you are a solo dev with this skillset then maybe it’s a good choice. But in a team / big company setting such an unconventional stack will always be a drag chute on your velocity in all stages of the project
