Transpiling is here to stay... there is no acceptable ROI for 'move fast and break things'. It's for organizational and economic reasons, not technical ones. Even if the browsers catch up, it can still take a year or more for roll-out updated software in many companies. It doesn't seem like you're aware of the fact that in an enterprise, 99% of users aren't allowed to install and update software on their own.
Perhaps, but I run an entertainment site targeted towards consumers. You'd think that we'd never need to support IE8 or even IE9, right?
Well no, about 10% of our traffic is from people sitting on those two browsers at work. Some of those people are even still running Windows XP, forcing us to use SAN instead of SNI certs.
There's a few traffic spikes in the day. Pre-8am, when people check the site before work. 12pm when people are fiddling around at work, then post 5pm when people are home from work, then 10pm before people sleep.
We even have a web app, but nope, people prefer to use the desktop version even at work.

This depends on many things. If your 90% brings enough profit, then this 10% perhaps could be dismissed, as it might not be worth the developers costs and time to keep support them (that needs an "opportunity cost" calculation).
There's also the fact that that 10% is only gonna go down, never up again.
