MFL departments are closing and exam entries are going down. However it’s very good advice to add a MFL in as joint honours. Universities would like to keep their departments open and offer as many as possible. Adding a MFL into a competitive course often helps get an offer. The universities want linguists.
DD was a bit put out by one of her interviews, the chap focussed in on the fact she'd done German gcse... only because her school made them do an MFL and it was one of her B grades so no, she wasn't interested in signing up for 'engineering with German' . not her thing, and it didn't stop her getting an offer but I assume could have been helpful to a slightly borderline applicant, and I'm sure it's a great opportunity if you've got the aptitude. Though maybe doesn't help with the brain drain of engineers to European countries which value them more, thinking of your earlier observation!
Her course, and I'd guess many, allows languages as a module option in one or two years. Her BF did an initio Japanese.
This seems like quite a sensible way forward, to add on language skills for those who want to communicate but maybe not engage with literature. But I hope that good language departments continue - not just MFL but mediaeval Italian, ancient Icelandic or whatever too, at appropriate scale.
