Yesterday me and a friend were talking about the overuse of custom taglibs!

We create taglibs for everything! We create taglibs in order to wrap jQuery UI elements (tabs, button, etc), and other plugins elements as well. We often wrap them together in a single component. We use taglibs in a point that we almost have no pure html within the body tag.

Our question is: is this a healthy habit??? Imagine two situations:

1) We hire an html designer and have the cost of a month for him to learn all this stuff.

2) We want to outsource the html development but no company would get our taglib library to learn, OR it become more expensive.

We love taglibs as its been a lovely shortcut for javascipt development as we write it only once. What would be the best practices in this sense, and what would you suggest? We are looking for a future-proof solution (or an argument that agrees with ours).
