Those definitely are up there as well and you pin-point their exact problem; they alter the game-play for the worse.
In my opinion? No, these modifications you mention do not enhance the game-play in any way, they cripple it, get rid of it. It feels like some brain-storm session team forced themselves into thinking about X amount of modifications to add without ever (really) playing the game. In skilled hands / teams these modifications are mind-blowing additions. The ones you might "fix" from that amazing think-tank session are; tagger, mobility sling and high magnification scope, I'd say.
For example, high magnification scope; maybe go for something like plain zoom-mods in different categories (high magnification isn't the worst but it shouldn't be behind rank 195 and the zoom factor is locked to a rate suitable mostly for launchers, great stuff. Yeah I'd remove this one if it was up to me and go back to the drawing board).
And completely different new stuff: like, specific arresting / burglar modifications, for example something that would multiple gains for cops and somewhat higher always-witnessable stack possession for criminals so that cops can finally farm solo and as for crims the 'stack solution' G1 added was just a band-aid which made farming on empty servers a really important thing... way to go. This part of the game could use more TLC, modification exploration in my opinion. I'd even go as far as modifications to help new people; free car spawns, more gains ( as in money / exp / jokers modification mods, cumulative with any premium package).
I need a fresh coke but first let's see what runner is crying about now.
