I concur with this webinar being an excellent explanation between operating IFR in IMC vs IFR in VMC as it applies to SLSA and ELSA aircraft. Bottom line was the ASTM standard for LSA prohibits IMC operation, which applies to the ELSA operating limits defined in the RV-12 POH. The POH specifically states operation in IFR/IMC is prohibited. Apparently the lack of a specific prohibition on IFR/VMC means you can fly/file IFR (if so equipped) as long as you remain in VMC.
If you build EAB, you can have OpLimits/fly IFR/IMC if 91.205(d) is complied with, which is what I did. Answering the OP, I installed a heated pitot tube in the wing with quick disconnect fittings to retain the removable wing capability. The Dynon Skyview AP can fly a coupled approach with my IFD-540, the only part missing is an auto-throttle to control speed. I do not fly in IMC, however it is nice to have the capability if I ever get in a VMC to IMC situation.
