That's fair, but I think that XF has a good story around integrations with other frameworks to fill its gaps: SkiaSharp has the SkiaSharp.Views.Forms namespace, for instance, and there's solid documentation on integrating the two, right there on Microsoft's Xamarin.Forms docs. Actually, speaking of docs, Charles Petzold's book on XF is an awesome resource -- I've not seen commensurate investments in documentation made by XF's competitors (admittedly it's not something I track that closely). Similarly XF's ability to add a native control directly to a StackLayout via extension methods makes it fairly straightforward to just drop in a native component if that's what you want to do.

I think it's a reasonable strategy to say "hey, we're not going to be able to solve all the problems, and it's probably not the right way to spend our time even if we could. What we will do is make integration with other solutions straightforward so we're not the bottleneck". Making a strategic choice not to be the bottleneck seems like a good call regardless. That said, the things I've found to be a hassle are things like getting OpenGL working on UWP from C# (tractable, but that's really not how I want to be spending my time).

But yeah, wow what a difference it's made having Microsoft throw their resources at it. My current codebase lets me build for iOS, Mac & UWP at present (I'll get to Android at some point), with really not very much effort. Being able to debug on the Mac version rather than waiting for iOS deploys is just about enough to repay the time investment on its own. I'm anxiously awaiting them getting their web platform support up to snuff -- I'd dearly love to never have to JavaScript again. :)
