Service Application for mobile (and TV) web apps should be supported.

This feature is supported in wearable web apps only atm:

https://developer.tizen.org/development/guides/web-application/application-management/applications/service-application

We need this for mobile (and TV) messaging web apps, which are often requested by users:

Telegram: https://github.com/zhukov/webogram

Matrix (including IRC, Gitter and webRTC video calls): https://github.com/vector-im/vector-web

Mattermost: https://github.com/mattermost/mattermost-mobile

Rocket Chat: https://github.com/RocketChat/Rocket.Chat

etc…

Thanks
