You're essentially re-applying, so all the same stuff you had to provide at application. Much easier to just take a little vacation somewhere outside of Thailand.
Personal opinion and experience: submit what they ask for. I don't think they're looking for reasons to deny everyone. They're simply looking for reasons to deny people who *abuse* the system. Consulates differ, but this is the pragmatic viewpoint I'm using on my journey to Thailand (from the US; Chicago). ❤️
