It's first time such a comprehensive EW system got installed on a fighter (and there are still only a few), and got fused into fighter combat systems so deeply on top of that.
1990s were sort of revolution in this sense, because effective and compact DRFM jammers (especially israeli ones) proliferated a lot; before that, such jammers were exclusive feature of some strategic bombers(where it was "fuzed" through dedicated operator, something no fighter can afford).
Rafale joined led the trend - just check how rich its suit of emitting antennas spread across the airframe. It byitself is an elaborate flying self-protection pod, with rich apperture space in best suitable locations, etc.
Even now, only one fighter suit is clearly ahead in complexity, volume and power (Himalayas), and there is a comparable (more advanced) competitor emerging (Arexis).
Other planes are more reserved - usually relying on jamming pods whenever necessary.
Opposite side - it's indeed a suit developed together with Rafale. While power of jamming is important - ultimately it doesn't neutralize targets with its weight and installed power - detection and jamming has to be on point.
This is one of the darkest areas in military domain, but overall - since 1990s, frequency hopping, recognition(ai!) and related techniques made incredible jump ahead, and all this happened afterwar SPECTRA appeared.
It's still a very potent system. But now the question of course arises, how well it kept up with threats and even types of threats which appeared after its appearence, especially systems french didn't consider as priority ones (Chinese MIC threat).
They should ve looked at least to some degree there - Rafale was designed more or less in parallel with F-22, and LPI isn't exactly magic (and deciphering LPI is not magic either - it's one of the reasons why such elaborate receivers are needed in the first place). But this is a digital competition, where you can fail, and where latecomer always has huge advantage.
Furthermore, some threats, like, Ku band LPI seekers, are something absolutely out of 1990s threat realm - this is a very 2010/2020s threat.
