Tinydns doesn't need patches to continue working after Feb. 1, 2019. The article website is about authoritative servers that give broken EDNS answers. You either want to correctly support EDNS, or send normal pre-EDNS answers. Both work, and tinydns does the latter. I don't know of any latest-version DNS software that breaks in this case. AFAIK this is exclusively a middleware problem, as is quite often the case.
