As https://www.ventismedia.com/mantis/view.php?id=9449 shows it's not been done yet.

I'm confused by the status of the ticket.
According to the roadmap it has been resolved with Release MM4 2021-02-22.
But I can't find the option in MM5.

According to the ticket it's still open:
https://www.ventismedia.com/mantis/view.php?id=9449

Has it been implemented in MM4 but then not in MM5?
And if so what is the new Roadmap for this feature?

I do use a custom field for this and then I set up a Magic Node to navigate by language.

But this approach has a big drawback: custom fields are not multi-valued. As I have lots of songs sung in two or more languages, I end up with nodes like "English; Portuguese" "English; Spanish" "Portuguese; Spanish" and so on...

A proper multi-valued "Language" field would ideal.

I agree, but would like to use the standard tag. The more so because there is such a tag specification mp3. In my music library at all mp3 files tag language is full. Some programs (MuzCat, Helium Music Manager) support it, so I would like MediaMonkey also had the support of the tag.

You could use a custom field or comment section for this.

Add support for the language tag the song. Many artists have Popular Sounds songs in several languages ​​(English, German, Spanish, etc.). Sample implementation is in Helium Music Manager.
