yad, how to create a simple question dialog?

I know yad can do much more than zenity, but it also misses quickies like --question. What is the simplest way to mimic that zenity option on yad? Obs.: mimic quickies for other possibly missing options are much welcome! *NOT REQUIRED:* As an opinion based answer bonus request, I would like to know if yad may resist the time, in a sense that zenity may last longer? I really want to implement scripts based on yad, but I would like to have an idea if it will still be maintained after 5 or 10 years? It seems that, ubuntu ppa at least, has auto-compile so packages may be auto-cooked fresh, is that also true? So basically, should I create something intermediary, where it will pop the dialog in yad or zenity (with severe functionalities limitations)?
