IMO, this discussion has become quite silly. Bottom line is that Alfred is probably not going to support Edge, so it's pointless to snipe at each other about browser-usage stats. On the bright side, Alfred does have that wonderful workflow capability, and I've found many built by others to fill various needs. chrome-bookmarks-alfred-workflow | Chrome/Canary/Chromium/Microsoft Edge bookmarks search workflow for Alfred (mdreizin.github.io) is the one I found to customize bookmarks search. I altered the shortcuts so that I get results from Edge with the shortcut-combo I'm used to. I highly recommend it.
Beyond that, though I would have liked native support for Edge, I appreciate the cautiousness of the Alfred team in what they add or don't. One thing I have found over the 5+ years of using it is that has rarely ever become unresponsive or slow. It's quite amazing, considering what it does and how it does it. And compared to many other mainstream software packages (I'm looking at you MS Office; and you, too, Mac Mail), it seems to maintain this stability year after year.
So, I'm now sorry that I originally contributed to this discuss, and I'll be un-following the topic.
Best to all.
