you pretty much answered yourself – hair instances are always scaled so their Y
bounding box fits the length of the hair it’s instanced on.
you can get around this by parenting the grass object under a (hidden)
cylinder, and instancing that. The cylinder’s Y bounding box will define the
scaling and you can freely scale the grass object underneath it.

Subject: Re: animating instances in place of hairs
The scaling of points or shape seems to work, but the result is then scaled
over the entire guide hairs.
I am trying to override this. I can't even figure out how to rearrange the
stack so that the scaling of the object
or points is done after the object is scaled to fit the guide hair.
For instance... if I scale the grass blade (the instance object group) in Y
then the grass field
has short fat blades that go the entire height of the guide hair.
If I put a deformation cage on the blade, it does deform, but is then stretched
to fit on the guide hair in y.

If you scale in other axes besides Y, does it work?
If not, what about scaling the points instead of its transform?

I would like to animate the shape of the blade of grass, as well, using the
shape animator.
Am I maybe not seeing the scaling of the blade of grass because hair always
tries to scale the y of the
instance to match the guide hairs? Anyway to override that?

According to the docs I can instance objects in place of hair and animate
them.
I am instancing blades of grass (in a group) to hair and any animated
scaling of the
instance does not translate to the hairs.
Is there a secret that I am missing?
I am following the docs, but some info must be missing.
Anyone?
