I'll keep this short and sweet:
Imho by taking away suppression (and maybe also as a side effect of the smoother experience through higher tick-/ simulationrate) the game feels even more fast paced or twitchy than it already did. I think in the current state playing very aggressive or constantly rushing is way too rewarding, the lack of suppression even further promotes the "cod- esque" playstyle.
I know "It's up to the server administrator to decide", but if I learned anything from quite some time in BF4 and BF3, then the overwhelming majority of populated servers will either use the exact server preset values or go crazy overboard with 4 alternating scrambler / autobalance addons, a knife yell- and a join announcer...
Realistically seen, any BF3 mod released in the near future will have a very small playerbase anyway, so most probably we will not have the luxury of setting up highly customized server setups and actually finding people to play those without extensive preparation and planning.
So in order to provide a consistent gameplay experience and not further separate the small amount of players, I'd highly recommend applying tweaks of some sort to slow the gameplay down and actually make it feel like battlefield and less like quake on large maps.
