[Tag Review] - Expected input/output languages #175
Description
From: w3ctag/design-reviews#1093 (comment)
This allows the implementation to download any necessary supporting material.
We’re worried about the risks of fingerprinting and excessive disk usage from letting the site select an arbitrary set of languages.
We tentatively believe that local models don’t need to be able to understand or produce languages outside the set that the user understands, and possibly the language the page is written in. That set could be downloaded with the main model without allowing the
LanguageModel.create()call to control the download—and potentially fingerprint the user’s browsing history—by picking different expected input and output languages. If we allow a site to use its own language, it could still probe by setting the page’s language differently on each load, but that’s much more visible. Is there a reason we shouldn’t believe this? If so, please add it to the explainer’s alternatives considered.
