Framebuffer and Vulkan / WebGL

Hello, I'm planning a more in-depth study of the GNU/Linux framebuffer. I'd like to ask if there are plans to add webGL functionality (even if in mobile GLES form, as in the SVG Tiny subproject) to Netsurf and, if so, would it still be able to run on the raw framebuffer? I see no mention of this on the Wiki nor any subproject related to it (except perhaps libNSFB?) Also, is there any interest in incorporating Vulkan in such an implementation? Thank you, Marco.
