A series of CSS3 text decoration properties implementations are currently on the works. These adds new properties which specifications are not finished yet, thus variable to changes. A new feature flag is required, with its boilerplate implementation handled in this bug and further bugs related to these implementations shall take advantage of this flag.
This bug handles the runtime flag of CSS3 text decoration properties (only available when compile flag is enabled, which comes enabled by default). The default value for the runtime flag is disabled.

Removing blocking bugs until further notice.
Given enough time to discuss about this need, I'm marking the bug as WONTFIX, as we're now relying just on build time feature flag (CSS3_TEXT).
