The article covers typo resilience in the section "Typo tolerance / fuzzy search".

This adds a step between query entry and text search where you find the similarity of query words to unique lexemes if the word is not a lexeme. Seems like a reasonable compromise to me?

I'm not trying to be argumentative. As long as people find a solution they're happy with, I think that's great. For me, I'm far less interested in handling typos, but I can see how it would be valuable in many applications. I'm usually less interested in tying in and learning another set of services if I can get 90% of the way there with one, but leaving the option of adding it later if additional requirements make it necessary.
