[webkit-dev] Place For new Core Module

[Maciej Stachowiak]

Given your description, I'm not sure this functionality is appropriate for WebKit. We are generally reluctant to take feature patches for features that are experimental or of niche interest - we prefer to focus on technologies that are part of the standards-based Web technology stack, that are likely to become Web standards, or that are valuable general-purpose complements to Web standards.

It sounds like the feature you are talking about does not fit this template very well currently, though it may in the future if it does get on track to become a Web standard.

Regards,
Maciej
