What theme are you using?

core

Is your feature request related to a problem? Please describe.

When the extraErrorsBlockSubmit flag was added back in the day, it was done to avoid a breaking change to how extraErrors affected the form submission.

Describe the solution you'd like

Given that users are likely to want them to block form submission, I recommend that we either remove the flag entirely OR change it to extraErrorsAreWarnings instead to switch the default behavior.

Describe alternatives you've considered

Examine the usage of `extraErrorsBlockSubmit` in the codebase. Remove it and adjust logic so that `extraErrors` always blocks form submission. Update tests accordingly.
