You mean upgrade the plugin without upgrading core..?
If so, that's yes with an if :)
Basically it depends on how old your core build is and whether the plugin depends on functionality that isn't present in your build. YMMV.
Sqlite back end is less travelled than mongo or mysql, so that probably goes to explain some of the twitchyness. Bug reports / PRs welcome to try and iron out some of those glitches!
