          In addition: looks like I was wrong that you can't have a change handler to check this right away.

Form fields are widgets and widgets can have players, therefore you can have a change handler.

See:

https://github.com/apostrophecms/form/blob/main/modules/%40apostrophecms/form-radio-field-widget/ui/src/index.js

For an example.

But if it is too messy to hook it up to error display it could be something we don't do right now.

I was also wrong about server side size enforcement, sorry!

It turns out that the entire upload is handled by the submitForm method in lib/process.js. So it is possible.

Currently though attachment uploads are processed in that method before the sanitization of fields, so it could be a bit tedious and I don't think it's a requirement that it happen in this release.
