There is some support on SE for rewriting links to a question with the question title; for instance, if I add a bare link of the form https://meta.stackexchange.com/questions/49433/replace-trilogy-raw-links-with-the-current-question-title
in the Markdown code it gets displayed as Replace trilogy raw links with the current question title? (see the link in the example itself for more detail).
It would be useful, in my view, to do the same for Wikipedia links; for instance, https://en.wikipedia.org/wiki/Isserlis%27_theorem
should be rendered as
Isserlis' theorem.
EDIT: since it has been asked in the comments, I'm pointing out explicitly some potential gains for the network: improved readability (for the links that the OP didn't bother to beautify by hand), less work to create posts (for the links that the OP did bother), and more helpful content (in those cases in which OP did not bother to add a Wikipedia link because they thought it was too much work to make it look good). There are examples in which it is not obvious to get to the correct Wikipedia page for a technical term (disambiguation), and even when it is, a well-place link makes life easier for the readers.

As this title is hardly of any use to anyone.
