Short description of error
There is a transform menu in pose mode in the Pose menu. it contains the transform To Sphere that does not work in Pose mode.

Exact steps for others to reproduce the error

Create a bones system
Switch to Pose mode
Try to use the To Sphere tool in the Pose menu.

Can confirm To Sphere, Push/Pull, Bend and Shear not working, will check.
Probably they need to have their poll corrected (because they are not meant to work in posemode) and excluded from the menu.

The bend tool hotkey also conflict with other functionality here. Shift W calls the bone options.

Please report this separately.

Looked into this a bit, transform code differences between posemode and editmode are not entirely clear to me here.
The td->iloc and td->loc (also axis?) are treated differently [or at least these have different assumptions/requirements].

One also needs to keep in mind, that pose "locations" are in relation to editmode locations, unaltered posebones have a zero-location even if editbones are transformed.
So these operators actually do something if the posebones are not in their restpose (dont correspond to editmode transforns), but it is either my limited understanding of posemode or the operators are not designed to work in posemode.

Tried feeding pchan->pose_mat- [x] into transdata (instead of pchan->loc), but this is a dead end as well, this would need to work with pchan->loc in the transform system.

Will step down to have others look at this (already was a bit of a time-sink), just noting that #87926 (Edit Mode operators are in in Pose Mode menu?) is a bit related.

From what I could understand in the Push/Pull operator, it only affects the location of the elements. So objects that have their location locked (such as bones) are not changed.
The translate operator has a fallback for rotate, so should Push/Pull fallback for scaling?

It is also important to keep in mind that the center cannot be equal to the location of the element as the Push/Pull brings the elements closer to the center.

So what I see about Push/Pull here is not a bug, but a misunderstanding.
I didn't see test the other problems (To Sphere and the hotkeys).
I think they are different problems and should be reported separately?

I noticed that the hotkeys have already been reported separately, so I edited the description.

If the bones are not parented, they are free to move, but still this is behaving unexpectedly, see
#88342.webm
To Sphere wont have any effect at all in the above "free" case.
And it is not only because in editmode it works on head and tail, it is the difference in handling td->loc / pchan->loc etc afaict.

And as I said, it gets really "interesting" if the posebones have their own transform on top of editbones prior to using these operators

In fact, in pose mode, the position of each bone (in td->loc) is relative to the rest position, and the actual real position is td->center. Although it works in some modes, this is not the convention of the transform operator.
Deserves an investigation.
