That wording sounds fine to me. I don't think we can reasonably expect to hear from Jake again, but from my understanding of his post, this addresses his concerns.

FWIW, I share those concerns. My brain can't parse "robust estimator for central location", because the term "estimator" has a precise and well-defined meaning in (frequentist) statistics, and what I expect to see after "estimator for" is a description of a parameter of a statistical model - as in for example "estimator for the population mean", or "estimator for the Weibull shape parameter". "central location" doesn't really fit in that slot.

I can't think of any good reason not to. We have plenty of other external links in the docs, and the Wikipedia links are probably at lower risk of becoming stale than most of the others.
