I don't know how it is hard to keep support for an OS that chrome/chromium has left since a long time, but for my part I understand developers who can't say, for sure, they will support a 14 years old OS, for 2 years 7 months 3 days 2 hours 25 minutes 37 seconds...because it doesn't depend only on them. If chrome/chromium delete big parts of features made for old OS support, Centbrowser developers will have a lot of work, and it will be worst and worst, and releases will be (more) delayed 
Just to be clear, of course I would like to have an updated centbrowser, like everyone here.
(and like everyone, I don't like this feeling when I hope for something, and it doesn't come)
BTW, one small correction...you are NOT a customer, you're an USER of a free browser made on free time of free developers.
so there is absolutely no "good customer relations", only "good USER relations". Semantic is extremely important here.
