The same could be said of a Pup, but it is still cleared for IFR use. The workload is higher than say a 172, but even my MCR can be flown IFR in the US and they regularly are. In simulated conditions, I have managed a "theoretical" IMC renewal in mine.
I have to say I have no real strong desire to get mine IFR approved. I will never bother with an IR, unless the rules change dramatically, so IFR in Europe is not legal. The VFR rules are quite flexible and a single engine non de-ice aircraft has only limited IFR capability unless you are prepared to assume the engine will never fail.
