In my experience, using a framework and learning design aren't mutually exclusive. Learning a framework often requires studying its source code and grokking how it works, there's simply no better documentation. Granted that may not be quite at the level of designing your own complete framework from scratch, but imho it's the happiest middle ground between personal skill development and standing on the shoulders of giants that FOSS has enabled.
