Pragmatically, it does. I don't want to be forced to "get off the Chrome pony" right now as Chrome still is notably faster than Firefox on my computers (which are 5 and 8 years old but still do the job). If the next version of Chrome is the one that is going to break compatibility with extensions I use I'm just going to disable updates and this will give me at least a year - many people use even more outdated browsers are okay.
