Ok. I have more succinct question(s):
1. Which Thai embassies will issue Non-B visa without a wp in hand?
2. How serious have the Thai gotten about proof of work address? Will photos suffice, and do they want photos of me IN that location? 
3. During the 90-day inspection period prior to getting the 1-year, can and will they just show up unanounced, or will they tell you when they are coming? 
4. If something goes sideways, and the WP is a no-go, can I get another 90 days to get my ducks in a row, and if not, can I revert to 60-day METV? 
Thanks in advance.
TLDR : Answer Summary
The post discusses the issuance of Non-B visas without a work permit, specifically noting that currently the Thai embassies in Hong Kong and Ho Chi Minh City will issue a 90-day Non-B visa without requiring a work permit or WP3 receipt. It highlights evolving standards concerning required documentation, including whether photographs are required at the applicant's work location and the expectations for inspections during the visa process. Additionally, it touches on the potential for visa extensions if work permit issues arise.
