Yes, I've been doing this for a long time now and I've also helped convert several apps to the new SAF framework when the restrictions came out. I've also helped many companies and people with these kind of issues and in most cases it's been self-inflicted. The policy there was always very clear - you need to use SAF unless you're building something that absolutely function with it (these are pretty much exclusively file explorers). Syncthing can use SAF, the author just refuses to according to their bugs. This counts as "self-inflicted" and I'm not sure why they think they can complain their way out of it.
