Comment (by mcsf):

 > I mean, the least hassle would be letting the switcher disappear. Is
 that a viable option?

 My two cents as someone of a different mothertongue is that it's less
 about the switcher not being always available, and more that it disappears
 unexpectedly ("I thought there was a thingy to change the language?")

 > The first one requires overriding the parent theme's template-
 parts/navigation/navigation-top.php so that it includes the language
 switcher template tag, plus a reworking of the CSS grid.

 I'm not familiar with this domain, but is the parent theme
 `twentyseventeen`? Because, if so, changing it doesn't sound like the best
 idea. Or is the parent some other niche theme with less inertia that I may
 have missed?

 Approach two seems viable. A drive-by suggestion, if you'd like to avoid
 duplicating the element-fixing logic from the parent, is to use something
 like `MutationObserver` to react to changes to `.navigation-top`'s
 classes, synchronizing with the local switcher.
