Creating native Slack client with the same features as current is not trivial. Just think all the apps, their embedded UI, voice/video calls. Likely the only reasoble way to have all this and keep it compatible with the browser version is to either build on browser or embed a browser in the native app. You can argue that all those things are not needed in a group chat, but Slack clearly feels otherwise. They are building a platform, some sort of groupware - not just chat. Check for example the Doodle bot demo: https://slack.com/apps/AFA5VQJKX-doodle-bot https://slack.com/apps/AFA5VQJKX-doodle-bot
