I don't see there being any issues with Covid extensions given people legitimately couldn't leave the country. I think the issue does arise when someone who was on Covid extensions until they were no longer offered has returned soon after and is continuing to try and live in Thailand on tourist visa exemptions/visas/extensions then it will clearly look to immigration like you're abusing the system.
By contrast, someone who was on Covid extensions until last September and comes back to Thailand for a couple of weeks and leaves again OR gets an appropriate visa won't face any difficulties.
Problem is on this forum, we're encountering so many people trying to live in Thailand without the appropriate visa. If they want to have an easy way of extending their visa and they're not working (or working remotely) why don't these people try Cambodia or Laos? Its much easier to extend visas there and though it's a system using corrupt agents it's all tolerated and nothing will be done to change or Crack down on the system in the foreseeable future. Everyone extends using an agent in Laos and Cambodia.
