I also hear from large node operators that it is still the Exit flag

So, what do people think? Does anyone violently disagree with removing
the Guard flag from Guard+Exit nodes?

I wondered how many guards would we have before and after this change:

1021 Exits

1725 Guards

* 412 Guards that are Exits

* 1313 Guards that arenât Exits

This would be a 24% decrease in the number of Guards, which seems ok, particularly if theyâre not good at being guards anyway.

(Counts from the 2015-09-24 21:00:00 microdesc consensus in my local Tor Browser data folder.)

Would we also want to disable the DirPort on Exits? Or is that a small amount of extra load?

Similarly, what about the HSDir flag?
