Security guarantees are nice but only if there believable. If the last 3 years have shown anything it’s that the west will not go to all out war with Russia over Ukraine. It may make putin more hesitant but if he calls our bluff a piece of paper isn’t going to change the fact that Americans and western Europeans aren’t willing to die for Ukraine.
Depends on where the burden is being placed. If it’s adding more hoops for everyday people to jump through to get what they need, no. If it’s adding more hoops for large organizations and corporations who can hire people for compliance, yes. If it’s just hiring more people on the government side to analyze the existing data, but the forms and processes stay the same on the other end, sure.
