Persistent VTY history?

Hi all. Was just thinking today about if it was ever considered to write the VTY history out to a file on exiting (and load it on startup) I'm quite the fan of the up arrow and it's been something that sometimes annoys that I have no history after leaving the VTY. It would seem reasonably trivial to implement, and I suppose you could write out to files in $HOME/.osmo-bsc_history or $HOME/.config or somesuch. Just wondering if this was ever discussed before, if there's any unforseen problem with it on my part + if it would be a desirable feature for anybody else? k/
