Desirable difficulty could perhaps be linked with the ability to recall information. It appears that the presence of serif markings has a correlation with information recall. Apparently, texts written with serif appear more straight, and thus easier to read (and remember). This was found true for longer texts.
Thinking of long texts that I had written last year, I remember the QA report I completed back in October. The whole report was about 50 pages long and I remember the chief assessor mentioned that she did not like how the report was presented. Perhaps it is because it was difficult to follow due to its length plus it used Calibri - a font that is (almost) sans serif. Aside from the ability to recall, maybe what I am seeing here is 'desirable difficulty' at play - where the chief assessor has no motivation because of the lack of serifs to help with the pace of the reading, and the use of sans serif fonts which are yet to be common to long texts.
