Given that I play almost entirely CQB and regularly get point-blanked with that energy (and a maximum mass of 0.25g) then no, not at all.
I think that's about the right limit. If you go down the Septic route of 2J AEGs then you get into MEDs and those rather silly "BANG! BRO! I BANGED YOU!" videos that you can see on the YouTubes when they get up close.
UK law allowing, which it doesn't, then in woodland I think you could make an argument for raising bolt power to 3J or even more to allow for longer ranges in conjunction with 30m MEDs. However, I wouldn't make that argument because you should consider the worst case, and the realistic case, rather than the best case. With airsoft inability to judge distances, the push towards denser and denser BBs, and the risk of someone popping out of cover and getting point blanked in the face, I think 500fps is about right too.
Actually, if you want to make distinctions between AEG, DMR and boltie ranges, one way to do that would be to limit BB weights. In the nightmare scenario that we went full NI / Italian with a flat 1J limit, you could limit AEGs to (for the sake of argument) 0.2g, DMR to 0.28g and bolties to... well, let's get to that... and you'd get extra range even for the same energy.
On weight, I'd like us to have a think about BB weights, and what they're actually composed of. The natural weight of an ABS or PLA not really bio 5.95mm BB is about 0.12g. Anything above 0.2g is adulterated, and above 0.4g you start losing the argument that you're actually slinging plastic. Remember, a steel BB is 0.86g.
I use exclusively 0.2g in CQB. On the occasions I play outdoors I have 0.43g in the boltie, and I'm rather thinking that if I put my range where my maths is that I shouldn't. But then... everybody else is, so I wouldn't be competitive. It's an issue for sites and the hobby in general.
