I think we don't, but I'm not sure.

It's a bit questionable. For example, the error you mention above
is clearly a bug in frontend. Presenting a translated version of
that message to the user is essentially pointless. On the other
hand, "Thread is running", or "Memory not accessible" messages
can be helpful for users. Do we need two error messages, maybe?

sizeof? For all I know, sizeof("--thread") will be wrong here.

Why would frontend want to specify frame level in hex?
