While this change isn't inherently bad, the correct solution that just hasn't been done is to have this function return an AppInstaller::StringResource::String, then have a function to get the internal, non-localized string message from that string name. The CLI paths would prefer to get the localized resource value, falling back to the internal path if one isn't present (and hopefully never needing to do that).

Not expecting you to do any of this, just dumping my "we should do this one day" thoughts out there...

I completely agree with you; Definitely something to add to the "To-Do" list. If I have time this weekend I can look into that (maybe)

Nit: can you remove the extra line, not sure if it's github's apply suggestion issue.
