Currently we have a custom TextMarshalerFlag. It's a nice idea, allowing anything implementing text marshaller to be used as a flag. That said, we only ever used it in one place because it's not that obvious how to use and it needs some boilerplate on the type itself too, apart of the heavy boilerplate got the custom flag. All in all there's no *need* to drop this feature just now, but while porting the cmds over to cli @V3, all other custom flags worker perfectly, whereas this one started crashing deep inside the cli package. The flag handling in v3 got rebuild on generics and there are a number of new methods needed; and my guess is that maybe one of them doesn't work like this flag currently is designed too. We could definitely try and redesign this flag for cli v3... but all that effort and boilerplate just to use it for 1 flag in 1 location, seems not worth it. So for now I'm suggesting removing it and maybe reconsider a similar feature in cli v3 with however it will work.
