GLSL is not part of Vulkan's value proposition and has no bearing on Vulkan's success. The competitive feature which Vulkan offers is it's non-proprietary nature and crosss-platform support. If it can deliver that with the same or better performance as proprietary solutions, and offering developers more choice about which language they want to implement shaders in, this is a clear win for Vulkan.
