Thank you very much for your detailed report about your experience obtaining a DTV E–Visa from the Thai Embassy in Vientiane, Laos under the Category of Thai Soft Power with Thai Cooking Classes
in fact, the TDAC QR Code is envisioned and in the future will most likely be required for more transactions, not just with Thai Immigration, but other Thai government entities, as stated in the draft regulations by Thai Ministers
in the original Thai language Ministerial Regulations implementing TDAC, several times TDAC is referred to as "TM.6 Online", thus any old Thai Immigration requirements needing the old Paper TM.6 Card will most likely ask for the TDAC QR Code (printed out hard copy) now and in the future

IMPORTANT:
Thai Visa is for entering Thailand. It is therefore issued to those who are outside of Thailand and will visit Thailand. Therefore, your visa application will be rejected if you are already in Thailand during the visa process.
Royal Thai Embassy, Bucharest has the authority to provide visa service only to those who are in Romania and Bulgaria for the entire visa process. Therefore, your visa application will be rejected if you are outside of Romania or Bulgaria.
No matter how talented the "agent" may be, the actual Thai E–Visa applicant should login onto the Thai eVisa website and find out exactly when the Thai Embassy/Thai Consulate scheduled the interview and go to the scheduled interview
if the Thai E–Visa applicant used an agent because they don't have the minimum proof of funds (money) and the agent "fronted" the money, well, highly doubt any Embassy/Consulate of any country would allow an "agent" to go to any visa interview in place of the actual Thai E–Visa applicant:
sure wouldn't work for their own country's Embassy/Consulate, why would it work for any Thai Embassy/Consulate??
Yes, unfortunately, more and more local Thai Immigration Offices want a "fresh copy" of the คร.22 /Kor Ror. 22, but great that your Thai Immigration Office takes only just the original!
That is a reasonable plan, as currently, it is very difficult to open that necessary Thai bank account in your name to obtain an Extension of Stay at your local Thai Immigration Office, if entering Thailand on a free Visa Exemption Stamp
If you make entry into Thailand on that Non–O (based on marriage) E–Visa from the Thai Embassy in London, then it will be much easier to open a Thai bank account by yourself
Don't forget to get a fresh copy of your Thai Marriage Certificate ( คร. 22 / " Kor Ror. 22 " ) at any Thai District Office as many Thai Immigration Offices would need that as part of your Extension application process
