Hmmm... The 100-300, 1200 f/8, 5.2 VR, 28-70, 600/800 f/11s, 400 2.8 and 600 f/4 aren't innovative? Nevermind the top shelf optical performance of most of the RF lineup.
Honestly, IMO for several of these the answer is no they aren't. Nikon came out with a 120-300/2.8 a few years ago, Sigma has had one for almost 20 years, and an extra 20mm on the wide end isn't much of an innovation. The RF 400/2.8 and 600/4 are mainly just the EF MkIII versions with an adapter bolted on, and the RF 800/5.6 and 1200/8 are those same lenses with a bespoke 2x TC added in along with the bolted-on adapter. Not a whole lot of innovation there, either.
The 28-70/2 is certainly innovative. The 5.2mm VR is innovative, albeit for a niche market. Most of the RF L-series lenses are modest improvements on already excellent lenses. An extra 1-2mm on the wide end of UWA zooms. IS added to the 24-70/2.8 (where IBIS is present on most bodies). 70-200 zooms with extending designs and materials making them smaller and lighter. 25% more focal length on the 100-500, but the same physical aperture as its 100-400 predecessor.
Personally, I think the most significant RF lens innovations are in the consumer range, particularly in designs that can keep the costs of those lenses low. The 600/11 and 800/11 are innovative, as are the RF 100-400, 15-30, and 16/2.8...in all cases bringing those focal lengths for FF bodies well down into the affordable range while maintaining really good IQ.
