More broadly have you though about a generic way to achieve/impart technical sophistication intentionally other than as a side effect of getting scraped knees doing technical things? I don't think there's any way to avoid getting a few battle scars, but just knowing about the idea of technical sophistication (and having a name for it) turns out to be a huge help, as you observed.
