All major application platforms have decent support for RTL, but more often than not it's up to a developer to use the built-in tools (or develop new ones if they had chosen to use a non-standard UI implementation). It might seem that supporting RTL is as easy as flipping a switch and calling it a day, but it's really not. Developers have to invest resources into supporting foreign (from their point of view) layouts. Interestingly, the issue seems to be similar to that of missing accessibility features. I believe the reason here is the same — if you don't expect many users who would make use of the feature, it gets overlooked.
