Ugh, imagine being an engineer on the project if it's the latter. At a company strategy level, it may be wise to put resources into having this ready to go. [1] At an individual level, putting tons of effort into something like this with less than average hopes of launching seems extremely demotivating (and doesn't look so hot for "impact" in perf either).
I wonder how much effort it is combine the iOS UI layer and the non-iOS blink layer. I'm terrible at estimating effort even for my own projects so it's hard to speculate.
[1] A bit less wise to do speculative projects while simultaneously laying off 12,000 people with no warning.
