I have proposed changing the default to -1 in order to preserve

SInce the usefulness of a long list seems questionable, I'm leaning
towards an info log + truncate. I based my reasoning for the behavior
on the maxParameterCount attribute, but the difference is that a
request cannot be executed with only half the parameters. OTOH,
languages is a user thing and will not functionally break the request.

We have also seen this pop up in production.
I like limiting locales without aborting the request as a way forward.
Regarding the limit itself, 10 seems like an okay limit to me for languages
people would actually specify.
As Enric hinted at in [1], browsers tend to add fallback languages to
the list,
i.e. I specify "German (Germany)" and my browser sends both "de-de" and
"de".
So worst-case the browser would double the length of the user-specified
list.
With that in mind, I'd suggest a default of 20 (or so).
Kind regards,
Konrad
