If the libs are called Barracuda and Seagull you'll have to spend years telling people "although you have heard of Barracuda, the lib you want to use now is Seagull", I don't see that as very different. People don't make library choices based on the name only, they search for what is recommended online and look at examples/features/etc. I do concede that all else being equal people will gravitate towards the more "official" sounding library, but if all else's equal, it's not really an issue.
