Honing mine a conservative 50 /51 degrees, I haven't really found a down side for the two planes I use,
(not my rougher set jack-scrubby plane)
The cap iron actually working, on my Bailey planes, means less effort for me, as the plane doesn't get halted.
That's my 5 1/2 with no greater distance than 1/32" from the edge, heaviest shaving practical, in densest example of interlocked timber I use below...

And smoother with no greater distance from the edge than 1/64"

The "no greater distance" is importantly related to the camber of the iron, i.e, I can't set the cap that close if the iron is more cambered,
as the corners of the cap would overshoot each side.
(That's with the cap honed at 50/51 degrees. and I haven't played around with going steeper in order to attain more camber.)
and no tight mouths for me.

BTW, Thanks Warren.
