Tests look very clean. Thanks this already great as it is, but I would prefer some slight changes to validation architecture -- separating HTTP logic from validation logic. Important as we'll add more such functionality going forward, good to have the API clean now.

The most elegant solution is to change the default value for config.features.spontaneous_file_upload to always be populated with SpontaneousFileUploadFeature then to have enabled default to False and move max_files and max_size_mb default values from the frontend to the backend config. This would remove the if ... is None in favour of more explicit code. But I get it if perhaps that's out of scope and left for a later PR.
The second best would be to follow the frontend in this and not allow uploads unless explicitly enabled. Definitely, we should try to avoid having a TODO in a PR. ;)

The current behaviour for the e2e tests is that it is None. So rejecting upload when it is not configured will break the tests and might also break things for users.
I agree that the best would be to not have None as the default, but this indeed seems out of scope.

Where would you put the validation logic? |
This is what I referred to in that comment: #1459 (comment) |
