Provide clear support statement for SPFx with IE
Right now there is no clear statement regarding the supportability of IE with SPFx. Since IE 11 is still supported for O365 and SharePoint Online, customers assume that it is supported with IE as well.
Currently SPFx is impossible to use with IE because of performance issues and very bad memory leaks in IE. The more content and web parts are on a modern page the worse it gets. Thus, I suggest that you either fix those issues, or make a clear statement that SPFx is not supported with IE anymore. This would really help customers in making their decisions.
We have now provided explicitly supportability statement for the IE 11 in the context of SharePoint Online at following location: https://support.office.com/en-us/article/which-browsers-work-with-office-for-the-web-ad1303e0-a318-47aa-b409-d3a5eb44e452?ui=en-US&rs=en-US&ad=US
“Modern pages, lists and libraries on SharePoint Online are only supported in Internet Explorer 11 when Document mode is set to Internet Explorer 11”
Other browser modes are unfortunately not using modern web technologies and are not supported as such.
If you find any issues on the SharePoint Framework capabilities with IE 11 which is in the IE 11 mode, please open an issue at http://aka.ms/spdev-issues with sufficient details, so that we can provide support for your issue.
Hopefully that provides the needed clarity on the situation.

Not sure where this message is coming from, but we are certainly NOT wrapping up SPFx development and want to be quite explicit on that message to avoid any confusion or unnecessary rumors.
We actually keep on increasing investments on it all the time.

It is very clear that SPFX is not supporting IE but unfortunately customer is asking for support. We don't know what to do with this, really annoying issue.
I have heard recently that the team is wrapping up SPFx development and moving towards efficiency improvements and finalising the framework and tooling.
We have found that we can keep IE happy if pages are kept to as few web-parts as possible and to advise clients to use modern browsers where possible.
This is an issue inherent to modern stateful frameworks and IE will always be an issue here. They certainly can make improvements to SPFx but I very much doubt it's possible to get parity between a modern browser and IE11. We seem to experience ~4second render time for IE11 in a fairly populated modern page. Not great but our clients can survive if they're adament on using IE11.
