From a point of view of light traveling at the 'speed of light', I prefer to see it as 'light' traveling at the 'speed limit of the universe'. I don't see the 'speed of light' as the limiter.
I see the speed limiter being the speed limit of the universe. I believe that if the speed limit of the universe became faster than its current limit, then light would travel faster to reach that speed limit.
I suppose now that I think of it a bit more, if light were to travel faster than its current speed through a vacuum, then time would have to slow down to compensate, or perhaps time would have to go backward in order to increase the speed of light? It's a fascinating 'place' we live in.
