Yes, that is too much to ask. When laws were introduced fit the accessibility of buildings did the government then build employees of accessible buildings for people to copy? You will indeed see examples of compliance, but from game developers, not government. For all the talk of indie burden what you're going to see is some AAAs who have no ability to argue unreasonable expense because of the size of their wallet jumping the gun and producing fully compliant systems ahead of when they're required to, going for 100% even in games that were already far through development when Jan 1st hit. Those examples can then be learned from and copied. Those companies are essentially shouldering the R&D cost for the rest of the industry.
