It makes sense to me that the corps would want that. It doesn't, however, make sense to me that it can't be hotwired by a Decker with Hardware, who jailbreaks my Chemical Seal to accept my wired trodes/datajack signal to employ faster.
Meanwhile I stick with a second commlink for communications only, which can still be hacked to feed me fake messages or attack me with a soundburst not unlike a flashbang, or disable my flare compensation and toss flares my way because I took the risk to accept Image Link input from my teammates.
As for Cloud Computing, I still would like to have the expensive option of wiring my cloud computing options into a cyberdeck. Give me a rule on how many of these calculations each deck level can run for me, so I know whether I lose my vision enhancement bonus when using my smartgun, and I know at the least that I can pay a big chunk of money to run my gear together.
And I don't mind that previous functionality in SR4 isn't there anymore in SR5, because they changed the mechanics, not just the technology. The 2074 model does exactly the same as the 2075 model when offline, because it works in the SR5 mechanics. The 2075 model, however, as well as previous models that get a firmware update, apparently got some more stuff now. And I have issues with the justifications for some of those.

Now something else I need to note: Limit modifiers mostly replaced dicepool modifiers. And I really, really, really like that. You only need to get them if you're good, can ignore them if you're not. +2 dice? Everyone needs that. +2 limit? If I got a pool of 9 and a limit of 6,
one out of every 120 rolls will be limited. Do I really need to increase that? I'll pass.
Adding the dicepool modifiers back in after that is urgh. Which is why my first houserule move, which at this point I'm 95% certain I'll make, is to start by removing all dicepool modifier wireless bonuses out of the game. No matter whether you're wired, wireless or offline, all you get is the limit modifier. The dicepool modifier is gone, dead, out with the old.
In with the new would be hacking rules for communications. If you want to chitchat with others, expect a rule that lets enemy hackers send you wrong intel that cause limit penalties or even blatantly lie to you and trick you into making a really dumb move. Even if you keep your gun and ware offline, I'm pretty sure you still tend to not run radio-silent so there will be possibilities there.
As for Chemical Seal and other things like it: I'd simply make rules regarding how wires just LOVE sprinting and climbing and gymnastics and you getting hit with flechette ammo, so even if you jailbreak the stuff to work through trodes/datajacks, there will be consequences to the wired approach too.
And with that, I still give the hackers clear-defined new opportunities, there's cost/time/risk constraints to the protection mechanisms and I stick with the whole "forget dicepool modifiers" feel that I love.
