Yes, but part of the beauty of the new system is just having to say
"--sparse" to make something useful happen. :)

Agreed. 1-3 look obviously correct to me. The quoting bits I'm a little
more fuzzy on, just because I haven't really looked hard into cone mode.
Ditto for the "disable cone mode" checks.
My gut instinct is that you should be able to deduce whether the pattern
hashmap can be used purely from the patterns you see, and
core.sparseCheckoutCone would not be needed (and so if you violate the
rules by writing something manual, then it just gets slower; or maybe
we're even able to apply the literal cone-mode rules quickly and handle
the other separately). But it's much more likely I'm showing off my lack
of knowledge of the details of the problem space. You can feel free to
educate me, and/or roll your eyes and ignore me if this was already
discussed earlier.
By the way, I did notice this while poking about, which could go on top
(or hopefully be lumped in with the 1-3 as "obviously correct"):
